One of these agreements deals strictly with work in Utah. Parties to this agreement are Utah Division of Wildlife Resources (UDWR), U.S. Fish and Wildlife Service (USFWS), U.S. Forest Service (USFS), U.S. Bureau of Land Management (BLM), U.S. Bureau of Reclamation, and Utah Reclamation Mitigation and Conservation Commission (Lentsch and Converse 1997). The other agreement adds work in other states and is known as a range-wide or tri-state agreement. Parties to this agreement are UDWR, USFWS, Colorado Division of Wildlife, and Wyoming Game and Fish Department (CRCT Task Force 1999). The Conservation Agreements have an appendage called the Conservation Strategy, which is an annually-updated plan outlining conservation actions to be taken over the next several years. Initial activities focus primarily on identifying populations of CRCT, determining their purity , and searching for potential reintroduction locations. Later work involves habitat enhancement, nonnative fish control, reintroductions, and monitoring. The document you are reading reports accomplishments and results of activities performed by UDWR Southeastern Region personnel during 2001. A proposed regional Conservation Strategy for 2002 is presented. SUMMARY OF ACTIVITIES Work during 2001 was conducted within the Southeastern and Southern Geographic Management Units (GMU) for CRCT (Figure 1). Activities occurred in these areas of the Southeastern GMU: (J) South Tavaputs Plateau (in the Price River and Green River Desolation Canyon drainages), (2) East Manti Mountain (in the Price River and San Rafael River drainages) , (3) La Sal Mountains (in the Upper Dolores River and Lower Dolores River drainages), (4) Abajo Mountains (in the Middle Colorado River and Montezuma Creek drainages), and (5) Henry Mountains (in the Lower Colorado River drainage). Work in the Southern GMU occurred in the Muddy Creek drainage of the East Manti Mountain area. Some accomplishments occurred ahead of the 200 I regional Conservation Strategy schedule, and others were in addition to planned work. A wide variety of activities was performed including: (I) electrofishing to : (a) find possible popUlations of CRCT (13 streams), (b) estimate fish population abundance (25 streams), (c) collect cutthroat trout samples for meri sti c and genetic testing (9 streams), (d) collect CRCT for di sease testing (6 streams), and (e) evaluate success of experimental tiger trout Salmo /rulla x Salve linus fontinalis stocking in fi shless waters (3 streams); (2) conducting visual surveys to: (a) find possible populations of CRCT (12 streams) and (b) inspect fishless streams to determine if they could be used for range expansion (12 streams); (3) evaluating habitat suitability of waters for CRCT (32 streams); (4) enhancing habitat for CRCT by completing a major stream restoration project (I stream); (5) conducting reconnaissance for a rotenone treatment/brood lake development project (I lake, several tributaries); (6) controlling the distribution and abundance of nonnative fish by: (a) removing nonnative trout collected during electrofishing surveys (5 streams) , (b) ceasing stocking offertile rainbow trout Oncorhynchus mykiss (a portion of I stream), (c) making plans to cease all Southeastern Region brook trout Salvelinus fon/inalis stocking beginning in 2002 (7 lakes), (d) inspecting fish migration barriers (6 streams), and (e) performing maintenance on a fish migration barrier (I strean1); and (7) obtaining support for chemical treatments, fish transplants, and other conservation actions by submitting applications/making presentations to: (a) Southeastern Regional Wildlife Advisory Council , (b) Utah Wildlife Board, (c) county commissioners/public lands councils (5 counties), (d) Governor's Office of Planning and Budget, (e) associations oflocal governments (3 groups), and (f) private landowners (2 individuals). SURVEY METHODS Electrofishing survey dates ranged from 24 March to 30 October, 2001. In all cases, electrofishing occurred when water flows and clari ty were considered adequate for 2 effective sampling. The number of sampling stations per stream ranged from one to five, passes from one to two, and segment lengths from 100 ft to 1.1 miles. Trout collected were enumerated and in most cases measured in total length to the nearest millimeter. Fish were not usually measured when the purpose of sampling was disease testing. Estimates offish population size were made for all streams. In cases where only a single pass was made with sampling gear, estimates were considered minimums. The Zippen depletion estimation technique described in Van Den Avyle (1993) was used to make population estimates with 95% confidence intervals where there were multiple passes. Visual surveys generally occurred in small streams and under conditions where fish coulcj be easily observed if present. Dates ranged from 7 July to 30 October, 2001. The length of stream searched ranged from 100 ft to 2.2 miles. Streams where electrofishing and/or visual searches occurred are shown in Table 1. At most streams where electrofishing resulted in the capture of cutthroat trout, samples were collected for meristic and genetic testing. Samples were not taken from streams where adequate sampling for such testing had been previously performed. Samples consisted of whole fish and/or fin clips. After samples were collected, they were held on dry ice in the field, then stored in a freezer for later transportation to UDWRs Salt Lake Office for distribution to meristic and genetic testing labs. Limited habitat sui tability information was gathered in conjunction with all surveys. Water temperature was taken on most streams, and in many cases mean stream width , mean depth, and water flows were estimated. Subjective ratings of substrate and cover conditions were made for all streams using standard criteria of UDWRs stream classification system. Cover ratings involved estimating the percentage of the stream with bank cover and shade, whereas substrate ratings were based on the percentage of the visible stream bottom comprised of gravel, rubble, and boulders. Streams with estimates of75-1 00% were given an excellent rating, 50-75% good, 25-50% fair, and 0-25% poor. ACCOMPLISHMENTS AND FINDINGS SOUTHEASTERN GEOGRAPHIC MANAGEMENT UNIT South Tavaputs Plateau - Price River drainage Electrofishing surveys in the South Tavaputs Plateau were performed in five streams of the Price River drainage (Hydrologic Unit # 14060007). The purpose of these surveys was to collect CRCT samples for di sease testing in preparation for transplants to the Green River Desolation Canyon drainage. Habitat suitability was evaluated in six streams. 3 Tabbyune Creek, Sections I and 2 contained only cutthroat trout (Table 2). Population estimates were 26-40 trout per mile in Section I and 200 trout per mile in Section 2. The Section 2 estimate is much lower than the 1,174 trout per mile obtained at a different site in 1998 (Berg and Slater 1999). However, the 200 I estimates were for a single electrofishing pass, in beaver-pond habitat, and it is estimated that the majority of fi sh escaped. Sixty samples were collected for disease testing and no prohibited pathogens were found. Section I had midsummer water temperatures of 62-69 F, estimated flows of 1.5-1.7 cfs, mean widths of 4.4-5.0 ft, mean depths of 0.3-0.4 ft, fair to good substrate ratings, and poor to excellent cover ratings (Table 5). Section 2 had a midsummer water temperature of 54 F, an adequate flow, a mean width of 16.8 ft , a mean depth of 1.2 ft, a poor substrate rating, and a fair cover rating. Only one cutthroat trout and three brown trout were collected in White River, Section I (Table 2). Population estimates for this stream were 0-6 trout per mile. These estimates are much lower than the 106 trout per mile obtained in 1998 (Berg and Slater 1999). Disease testing was not performed due to the scarcity of trout. Other species found included mottled sculpin COllus bairdi, speckled dace Rhinichthys osculus, suckers Catoslomus sp., redside shiners Richardsonius ballealus, and Utah chubs Gila atraria. White River, Section I had a midsummer water temperature of 63 F, adequate flows, mean widths of 13.1-25.5 ft, mean depths of 0.7-1.8 ft, and poor to fair substrate and cover ratings (Table 5). Cutthroat trout was the only species found in the Middle Fork of White River (Table 2). The population estimate for this stream was 528 trout per mi le. This estimate is higher than the 317 trout per mile obtained in 2000 (Berg and Slater 2000). Sixty samples were collected for disease testing and no prohibited pathogens were found. The Middle Fork of White River had a midsummer water temperature of 74 F (below the location where fish were collected), an estimated flow of2.4 cfs, mean widths of8.0-8 .6 ft, a mean depth of 0.3 ft, good substrate ratings, and poor to good cover ratings (Table 5). The Right Fork of White River contained cutthroat trout, mottled sculpin, speckled dace, suckers, and redside shiners (Table 2). Population estimates for this stream were 0-352 trout per mile. These estimates are lower than the 500-1 ,003 trout per mile obtained at different sites on the stream in 1998 (Berg and Slater 1999). Sixty samples of cutthroat trout were collected for disease testing and no prohibited pathogens were found . The Right Fork of White River had midsummer water temperatures of63-68 F, an estimated flow of 10.0 cfs, mean widths of 12.2-18.2 ft, mean depths of 0.6-1.6 ft, poor to fair substrate ratings, and fair to excellent cover ratings (Table 5). A major stream restoration project was completed on the Right Fork of White River to reduce erosion and sedimentation problems at a point where they begin in the headwaters of the Price River drainage. The project involved creating about 0.5 mile of 4 new channel to replace a portion which was severely degraded and downcut. Cooperators included UDWR, USFS, Utah Department of Transportation, Trout Unlimited, and a private landowner. Core conservation populations ofCRCT in the Right Fork of White River and its tributaries will benefit from the project. Several actions were taken to control the distribution and abundance of nOlmative fish. Stocking of fertile rainbow trout was terminated in Price River Section 5. Sterile triploid rainbow trout were stocked in their place. A request from a private landowner to continue stocking rainbow trout into Kyune Reservoir was denied. State stocking of tiger trout was offered as a temporary replacement for loss of rainbow trout in that water. Brown trout collected during electrofishing of White River, Section I were removed from that stream. Support was sought £i·om the Southeastern Regional Wildlife Advisory Council, Utah Wildlife Board, Utah County Commission, Governor' s Office of Planning and Budget, Mountainlands Association of Governments, and a private landowner for introducing CRCT into Kyune Reservoir beginning in 2005. South Tavaputs Plateau - Green River Desolation Canyon drainage Support was sought from the Southeastern Regional Wildlife Advisory Council, Utah Wildlife Board, Carbon County Commission, Governor's Office of Planning and Budget, and Southeastern Association of Governments for introducing CRCT into six streams and a private pond of the Green River Desolation Canyon Drainage. These waters include Rock and Bear Canyon creeks (2002); Flat Canyon Creek Sections I and 2, and Buckskin Canyon Creek (2003); Summerhouse Canyon Creek (2004); and Bear Springs Pond (2005). East Manti Mountain - Price River drainage Electrofishing surveys in the East Manti Mountain area were perfonmed in four streams of the Price River drainage (Hydrologic Unit # 14060007). Samples of cutthroat trout were collected for meristic and genetic testing from two of these streams. Trout survival was evaluated in the other two streams by searching for experimentally stocked tiger trout. Habitat suitability was evaluated in all four streams. Beaver Creek, Section 2 contained only cutthroat trout (Table 2). Population estimates for this stream were 0-158 trout per mile. Average total lengths were 208-224 mm (range 112-354 mm) (Table 3). Samples were collected from 30 fish for meristic and genetic testing (Table 4). Beaver Creek, Section 2 had late spring water temperatures of 46-62 F, adequate flows in three out of four locations, mean widths of 1.7-10.6 ft, mean depths of 0.4-0.5 ft, fair to good substrate ratings, and poor to fair cover ratings (Table 5). 5 Cutthroat and brown trout were found in Jump Creek (Table 2). Cutthroat trout comprised 75-100% of the trout catch. Population estimates for thi s stream were 343-634 trout per mile. Average total lengths of cutthroat trout were 155-163 mm (range 105-265 mm) (Table 3). Samples were collected from 31 fi sh for meristic and genetic testing (Table 4). To control the distribution and abundance of nonnative fish , brown trout collected during electrofishing were removed. Jump Creek had a late spring water temperature of 57 F, an estimated flow of 0.5 cfs, a mean width of 4.5 ft , a mean depth of 0.4 ft , fair to good substrate ratings, and good cover ratings (Table 5). Tiger trout experimentally stocked during 2000 into the North Fork of Gordon Creek were recovered (Table 2). The population estimate for this stream was 118 trout per mile, suggesting fair to good survival of the approximately 500 fish stocked. Average total length of tiger trout was 179 mm (range 140-205 mm) at recovery (Table 3) compared to 104 mm at stocking. Flow appeared adequate to support a CRCT population (Table 5). Experimentally stocked tiger trout were recovered from Mud Water Canyon Creek (Table 2). The population estimate for thi s stream was 440 trout per mi le, suggesting fair to good survival of the approximately 1,200 fi sh stocked into thi s formerly fi shless water. Average total length of tiger trout was 183 mm (range 69-234 mm) at recovery (Table 3) compared to 97 nun at stocking. Mud Water Canyon Creek had an estimated flow of 1.6 cfs, a mean width of 6.4 ft, a mean depth of OJ ft , a fair substrate rating, and a fair to good cover rating (Table 5). Support was sought from the Southeastern Regional Wildlife Advisory Council, Utah Wildlife Board, Carbon County Commission, Governor' s Office of Planning and Budget, and Southeastern Association of Governments for rotenoning a portion of the North Fork of Gordon Creek, and introducing CReT into that stream and Mud Water Canyon Creek, in 2004. East Manti Mountain - San Rafael River drainage Electrofi shing surveys in the East Manti Mountain area were performed in five streams of the San Rafael River drainage (Hydrologic Unit # 14060009). A visual survey was conducted in one stream. Samples of cutthroat trout were collected for meristic and genetic testing from two streams. Habitat suitability was evaluated in five streams. Trout survival was evaluated in one formerly fishless water by searching for experimentally stocked tiger trout. Boulger Creek, Section 1 contained cutthroat trout and cutthroat/rainbow trout hybrids (Table 2). Cutthroat trout compri sed 88% of the trout catch. The population estimate for thi s strean1 was 58 1 trout per mile . This estimate is lower than the 2,294 trout per mile obtained in 2000 (Berg and Slater 2000). However, the 2001 estimate was 6 for a single electrofishing pass. Average total length of cutthroat trout was 66 mm (range 47-143 mm) (Table 3). Samples were collected from 30 fish for genetic testing (Table 4). Boulger Creek, Section I had an early spring water temperature of36 F, an adequate fl ow, a mean width of 6.2 ft, a mean depth of 0.4 ft , an excellent substrate rating, and a good cover rating (Table 5). Cutthroat and brown trout were fo und in Rolfson Creek, Section I (Table 2). Cutthroat trout compri sed 97% of the trout catch. The population estimate for this stream was 147 trout per mile . Average total lengths of cutthroat trout were 130-172 mm (range 78-294 mm) (Table 3). Samples were collected from 30 fi sh for meristic and genetic testing (Table 4). Rolfson Creek, Section 1 had midsummer to midfall water temperatures of38-56 F, an estimated flow of 0.5 cfs, mean widths of8.5-9.5 ft , mean depths of 0.2-0.5 ft, good to excellent substrate ratings, and poor cover ratings (Table 5). No fi sh were found during electrofi shing and a visual survey of Rolfson Creek, Section 2 (Table 2). This stream had an adequate midsummer flow, a mean width of 13.0 ft, a mean depth of 0.6 ft, a good to excellent substrate rating, and a poor cover rating (Table 5). Flows reportedly drop to inadequate levels during winter, so Rolfson Creek, Section 2 should not be included in the Conservation Strategy. Fish were not discovered in Sawmill Canyon Creek (Table 2). This result is surprizing because a few cutthroat trout were collected during a 1999 survey (Berg et. al 2000). Sawmill Canyon Creek had a midsummer water temperature of 50 F, an estimated flow of 0.3 cfs, a mean width of2 .6 ft , a mean depth of 0.3 ft , a fair substrate rating, and an excellent cover rating (Table 5). It appears that Sawmill Canyon Creek has value as an occasional spawning/nursery area for cutthroat trout. Experimentally stocked tiger trout were recovered from Little Horse Creek (Table 2). Population estimates for this stream were 0-176 fish per mile, suggesting that survival of the approximately 570 fi sh stocked was fair in some portions ofthis formerly fi shless water and nil in other portions. Average total lengths of tiger trout were 138-178 (range 92-20Imm) at recovery (Table 3) compared to 104 mm at stocking. Little Horse Creek had early summer to late summer water temperatures of 43-55 F, estimated flows of 1.7- 4.0 cfs, mean widths of6.2-13.8 ft, mean depths of 0.2-0.5 ft, good to excellent substrate ratings, and poor to good cover rati ngs (Table 5). Several actions were taken to control the distribution and abundance of nonnative fish. Brown trout collected during electrofishing of Rolfson Creek, Section I were removed from that stream. Plans were made to switch stocking from brook trout to tiger trout in three lakes beginning in 2002. This eliminates all brook trout stocking in the San Rafael River drainage. Fish migration barriers on Scad Valley, Lake Canyon, Nuck Woodward Canyon, and Tie Fork creeks were inspected to determine if they were 7 functioning properly. RecolllJaissance was performed for a rotenone treatment to remove Yellowstone cutthroat trout from Duck Fork Reservoir and its tributaries. Support was sought from the Southeastern Regional Wildlife Advisory Council, Utah Wildlife Board, Emery and Sanpete County Conmlissions, Emery County Public Lands Council, Governor's Office of Planning and Budget, and Six County Association of Governments for conservation actions scheduled to occur in 2002. These actions include rotenoning, introducing CRCT into, and developing a brood lake at Duck Fork Reservoir; and introducing CRCT into Little Horse Creek. La Sal Mountains - Upper Dolores River drainage Fish migration barriers were inspected on two streams in the Upper Dolores River drainage (Hydrologic Unit #14030002) of the La Sal Mountains to determine if they were functioning properly. These streams were La Sal Creek, Section 3 and Deer Creek. Minor maintenance was performed on the La Sal Creek, Section 3 barrier. Support was sought from the Southeastern Regional Wildlife Advisory Council, Utah Wildlife Board, San Juan County Commission, Governor' s Office of Planning and Budget, and Southeastern Association of Governments for rotenoning four streams in 2003-2004 and introducing CRCT into them in 2005. These waters include Deer Creek, La Sal Creek Section 3, La Sal Creek Ditch, and La Sal Creek Ditch Main Diversion. La Sal Mountains - Lower Dolores River drainage Electrofishing surveys in the La Sal Mountains were performed in two streams of the Lower Dolores River drainage (Hydrologic Unit #14030004). Samples were collected for meristic and genetic testing from those streams, and for whirling di sease testing from one of the streams. Habitat suitabi lity was evaluated in both streams. Beaver Creek, Section 2 contained only cutthroat trout (Table 2), similar to a survey on Section I in 1998 (Berg and Slater 1999). The population estimate for Section 2 was 295 trout per mile. Average total length was 194 mm (range 105-294 mm) (Table 3). Samples were collected from II fish for meristic and genetic testing (Table 4). When these samples are added to samples collected from Section I in 1998, the total number of samples is sufficient for complete meristic and genetic testing. Beaver Creek, Section 2 had a midsummer water temperature of 48 F, an adequate flow, a mean width of 5.7 fI, a mean depth of 0.4 fI, and good substrate and cover ratings (Table 5). Cutthroat trout was the only species found in Geyser Creek, Section I (Table 2). This result is surprizing because brook trout were found in addition to cutthroat trout at a different site on the stream in 1999 (Berg el. al 2000). The population estimate in 200 I was 198 trout per mile. Average total length was 178 mm (range 70-280 mm) (Table 3). 8 Samples were collected from 30 fi sh for meristic and genetic testing (Table 4). Samples were also collected for whirling di sease testing but results are not yet available. Geyser Creek, Section 1 had a midsummer water temperature of 62 F, an adequate flow, a mean width of 8.7 ft, a mean depth of OJ ft , a good substrate rating, and a fair cover rating (Table 5). To control the di stribution and abundance of nonnative fish, plans were made to switch stocking from brook trout to tiger trout in one lake beginning in 2002. This eliminates all brook trout stocking in the Lower Dolores River drainage. Support was sought from the Southeastern Regional Wildlife Advisory Council, Utah Wildlife Board, San Juan County Commission, Governor's Office of Planning and Budget, Southeastern Association of Governments, and a private landowner for introducing CRCT into Geyser Springs Pond beginning in 200 I. A presentation to the Fish Health Policy Board is anticipated before the end of the year to seek approval for using Roc Creek as a source of fish for that transplant. Abajo Mountains - Middle Colorado River drainage Electrofishing surveys in the Abajo Mountains were performed in two streams of the Middle Colorado River drainage (Hydrologic Unit #14030005). Visual surveys were conducted in those streams and an additional stream. Habitat suitability was evaluated in all three streams. No fish were found during electrofishing and a visual survey of North Cottonwood Creek (Table 2). Natural barriers, including one waterfall about 20 ft high, make it unlikely that fish historically occupied thi s strean1. North Cottonwood Creek had a midsummer water temperature of 48 F, an estimated flow of O. 7 cfs, a mean width of 5.2 ft, a mean depth of 0.3 ft, a fair to good substrate rating, and an excellent cover rating (Table 5). This stream has adequate habitat to consider it a potential introduction site for CRCT. However, accessing it to stock fish would be difficult. Fish were not discovered during a visual survey of Trough Canyon Creek (Table 2). This stream had an inadequate flow, a mean width of 1.0 ft, a mean depth of 0.1 ft , a poor substrate rating, and an excellent cover rating (Table 5). Habitat is not suitable for CRCT so Trough Canyon Creek should not be included in the Conservation Strategy. No fish were found during electrofishing and visual surveys ofTuerto Canyon Creek (Table 2) . A waterfall was present at the lower end of this stream. This barrier, along with those downstream on North Cottonwood Creek, make it unlikely that fish historically occupied Tuerto Canyon Creek. The stream had a midsummer water temperature of 46 F, an estimated flow of 0.6 cfs, a mean width of 5.0 ft, a mean depth of 0.3 ft , a good substrate rating, and an excellent cover rating (Table 5). Habitat appears 9 adequate in Tuerto Canyon Creek to consider it a potential introduction site for CRCT. However, accessing the stream to stock fish would be difficult. To control the distribution and abundance of nonnative fish, plans were made to switch stocking from brook trout to tiger trout in one lake beginning in 2002. This eliminates all brook trout stocking in the Middle Colorado River drainage. Abajo Mountains - Montezuma Creek drainage Plans were made to control the distribution and abundance of nOlmative fish in the Montezuma Creek drainage of the Abajo Mountains by switching stocking from brook trout to tiger trout in one lake beginning in 2002. This eliminates all brook trout stocking in the Montezuma Creek drainage. Henry Mountains - Lower Colorado River drainage To control the distribution and abundance of nonnative fish , plans were made to switch stocking from brook trout to tiger trout in one lake begilming in 2002. This eliminates all brook trout stocking in the Lower Colorado River drainage. Some people may not consider this management change a conservation action for CRCT because it is unlikely that any trout historically occurred in the Henry Mountains. However, one stream (Crescent Creek) has adequate habitat to support trout and could be converted from a brook trout water to a CRCT water. SOUTHERN GEOGRAPHIC MANAGEMENT UNIT East Manti Mountain - Muddy Creek drainage Electrofishing surveys in the East Manti Mountain area were performed in seven streams of the Muddy Creek drainage (Hydrologic Unit #14070002). Visual surveys were conducted in eight streams. Samples of cutthroat trout were collected for meristic and genetic testing from three streams. Habitat suitability was evaluated in 12 streams. Cutthroat trout was the only species found in Beaver Creek (Table 2). The population estimate was 533 trout per mile. Average total length was 169 mm (range 43- 234 mm) (Table 3). Samples were collected from 30 fish for meristic and genetic testing (Table 4). Beaver Creek had an early summer to midsummer water temperature of 50 F, an estimated flow of2.1 cfs, a mean width of7.2 ft, a mean depth of 0.3 ft, and fair substrate and cover ratings (Table 5). No fi sh were discovered during eiectrofishing and a visual survey of Black Fork Creek (Table 2). This stream had a midsummer water temperature of 40 F, an adequate flow, a mean width of 10.0 ft, a mean depth of 0.3 ft, an excellent substrate rating, and a 10 good cover rating (Table 5). Low water temperature would probably not allow development of a CRCT population. Therefore, Black Fork Creek should not be included in the Conservation Strategy. Fish were not found during a visual survey of Box Canyon Creek (Table 2). This stream had an inadequate flow, a mean width of 4.0 ft, a mean depth of 0.4 ft, a poor substrate rating, and an excellent cover rating (Table 5). Box Canyon Creek should not be included in the Conservation Strategy. Absence of fi sh was noted during a visual survey of Cowboy Creek (Table 2). This stream had an inadequate flow, a mean width of2.4 ft , a mean depth of 0.1 ft, a fair to good substrate rating, and a poor cover rating (Table 5). Cowboy Creek should not be included in the Conservation Strategy. Fish Creek contained cutthroat and brook trout (Table 2). Cutthroat trout comprised 78% of the catch. The population estimate was 396 trout per mile. Average total length of cutthroat trout was 167 mm (range 65-252 mm) (Table 3). Samples were collected from 30 fish for meristic and genetic testing (Table 4). Fish Creek had estimated early sununer to midsummer water flows of 4.4-6.6 cfs, mean widths of 6.6-9. 1 ft, mean depths of 0.4-1.1 ft , poor to excellent substrate ratings, and fair cover ratings (Table 5). No fish were found during a visual survey of Greens Hollow Creek (Table 2). This stream had an inadequate flow, a mean width of 1.5 ft, a mean depth of 0.1 ft, a poor substrate rating, and a fair to good cover rating (Table 5). Greens Hollow Creek should not be included in the Conservation Strategy. Cutthroat and brook trout were found in Mill Fork Creek (Table 2). Cutthroat trout comprised 97% of the catch. The population estimate was 87 trout per mile. This estimate is probably low because little attempt was made to co llect juvenile-size fish. Average total length of cutthroat trout was 253 mm (range 80-350 mm) (Table 3). Samples were collected from 30 fish for meristic and genetic testing (Table 4). Mill Fork Creek had a midsummer water temperature of 58 F, an estimated flow of 5.0 cfs, a mean width of 14.1 ft , a mean depth of 0.4 ft, an excellent substrate rating, and a fair cover rating (Table 5). Fish were not discovered during a visual survey of the North Fork of Muddy Creek (Table 2). This stream had an inadequate flow, a mean width of 3.0 ft , a mean depth of 0.1 ft, an excellent substrate rating, and a poor cover rating (Table 5). The North Fork of Muddy Creek should not be included in the Conservation Strategy. No fish were found during electrofishing and visual surveys of the North Fork of Quitchupah Creek (Table 2). This streanl had a midsummer water temperature of 62 F, 11 an estimated flow of 5.7 cfs, mean widths of3.0-9.8 ft, mean depths of 0.3-0.4 ft, fair to good substrate ratings, and poor to good cover ratings (Table 5). At this time the North Fork of Quitchupah Creek should not be included in the Conservation Strategy. Fish were not found during electrofishing and a visual survey ofthe South Fork of Quitchupah Creek (Table 2). This stream had an inadequate flow, a mean width of 1.0 ft, a mean depth of 0.7 ft , and fair substrate and cover ratings (Table 5). The South Fork of Quitchupah Creek should not be included in the Conservation Strategy. Brook trout were discovered during a visual survey of Reservoir Creek (Table 2). This stream had an early summer to midsummer water temperature of 60 F, an estimated flow of 0.1 cfs, a mean width of6.5 ft , a mean depth of 0.1 ft , an excellent substrate rating, and a poor cover rating (Table 5). Reservoir Creek is often dewatered, making habitat unsuitable for sustaining a CRCT population. This stream should not be included in the Conservation Strategy. Slide Fork Creek contained only cutthroat trout (Table 2). The population estimate was 35 trout per mile. This estimate is low because it involoved a single electrofishing pass and no attempt was made to collect juvenile-size fish. Average total length was 272 mm (range 180-350 mm) (Table 3). Slide Fork Creek had a midsummer water temperature of 58 F, an estimated flow of 2.2 cfs, a mean width of 10.1 ft, a mean depth of 0.3 ft , a good substrate rating, and a fair cover rating (Table 5). To control the distribution and abundance of nonnative fish , brook trout collected during electrofishing were removed from two streams. These streams were Fish Creek and Mill Fork Creek. DISCUSSION AND RECOMMENDATIONS The Southeastern Region remains several years ahead of the initial conservation strategy schedule with regard to surveys. Surveys have resulted in the finding of 38 cutthroat trout populations in a total of 142.5 stream miles. Genetic testing has resulted in nine of these populations being designated conservation populations (28.3 stream miles), of which eight (23.7 stream miles) qualify as core conservation popUlations. Two populations (1.8 stream miles) have been found to have a moderate to high level of hybridization with rainbow trout and/or nonnative cutthroat trout. Twenty-seven populations (112.4 stream miles) still need genetic testing. We recommend that all remaining scheduled surveys to search for populations of CRCT, collect samples for meristic and genetic testing, and evaluate habitat be completed during years 2002-2003. We encourage fini shing genetic testing of all populations by the end of2003. We recommend that an exciting new phase ofCRCT management begin in 2002 : expanding the distribution ofCRCT. In an aggressive first year, we plan to treat two 12 waters with rotenone to remove nonnative trout and introduce CRCT into six waters (two lakes totaling about 48 acres and four streams totaling 10.7 miles) . One of these waters, Duck Fork Reservoir, will be developed as a brood lake to allow production of large numbers of CRCT for conservation and sport fishing purposes. Ten additional waters (one lake of about 20 acres and 9 streams totaling 32.8 miles) are scheduled for CRCT introduction during 2003-20 10. Accomplishing proposed work wi ll easily exceed UDWR commitments/long-term objectives for the Southeastern Region under the Utah and range-wide conservation agreements. The proposed 2002 Conservation Strategy shows work completed on each water and the timeline for specific conservation actions (Table 6). The individual status of all waters currently being utilized and/or considered for CRCT management is indicated in Table 7. LITERATURE CITED Berg, L. N. and M . T. Slater. 2000.
