June 30, 2008 <br />AvaiIable Data <br />Information regarding the current status of fisheries within BLM Segments 4 through 7 was <br />provided by the CDOW. CDOW has identified the following existing fishery information: <br />1) Fish Surveys <br />• BLM Segments 4 and 5: 1986 and 1992 (BLM Pump House below Gore Canyon). <br />• BLM Segment 6: 1912 and 2001 (at McCoy Cemetery); 1982 (from Big Alkali to <br />Burns). <br />• BLM Segment 7: 1995, 1996, 1997 and 2002 (at Dotsero); 1912, 1983 and 1993 <br />(2.5 miles below confluence with the Eagle); 1983 and 2005 (above Glenwood <br />Springs). <br />2) Fish Stocking <br />According to CDOW stocking data from 1973 to the present, the following segments of <br />the Colorado River have been stocked by the State: <br />• Rainbow trout have been stocked in Segments 4 and 5 (1981, 1984, 1989- 1993); in <br />Segment 6 (1973 -1978, 1981, 1984, 1989, 1990 and 1992 -4); in Segment 7 (1973- <br />1996 and 2002). <br />• Brown trout have been stocked in Segments 4 and 5 (1983); and in Segment 7 <br />(1973, 1980 -2, 1984 and 2001). There are no records of brown trout stocking in <br />Segment 6. <br />The data listed above does not include private stocking data. <br />Data Gaps <br />Some of the fish surveys were conducted before rainbow trout were impacted by whirling <br />disease and, therefore, may not properly reflect existing populations for the species. CDOW <br />plans to collect additional data within BLM Segments 4, 5, 6 and (possibly) 7 in the summer or <br />fall of 2008, if conditions allow. If the Management Plan Alternative is accepted by the BLM, <br />CDOW will develop a study plan to monitor the status of the fishery. The participants will <br />review this data along with existing data in preparing the Management Plan Alternative. <br />In addition, data to quantify flow needs for the maintenance and enhancement of the fishery is <br />lacking. The participants will evaluate existing sources of information to identify where further <br />studies are needed and will initiate the appropriate studies to determine quantifiable flow <br />protection targets for the fishery. <br />The participants have identified minimal data on both wade fishing and drift fishing. Data <br />collection on angling will focus on Segments 4 and 5 since these are the segments that have been <br />identified as possessing recreational (fishing) ORVs. The participants will assess the adequacy <br />of data from CDOW and will contact Trout Unlimited ( "TU "), U.S. Fish and Wildlife Service, <br />USFS, fishing clubs, and outfitters to fill data gaps as needed. This information will be used to <br />characterize existing access and assess the adequacy of access and facilities supporting the <br />angling uses on the river. <br />-11- <br />
