<br />monitoring and flow related studies; 3) providing technical hydrology swport for a <br />wide range of Recovery Implementation Progfam activities on a year-to-year basis; <br />4) providing support to other agencies in issues relating to flow quantification, <br />hydfology data, and report review; and 5) providing support to the Flaming Gorge and <br />Aspinall Biological Opinion Work Groups. <br /> <br />Recommendations: The work provided is, for the most part, in support of other <br />research projects or activities such as, flow delivery, flow quantification, and habitat <br />restoration which have a direct impact on the recovery of the Colorado River <br />endangered fish. The direct quantification of the success of many of the activities is <br />difficult because most of the activities are long-term in nature. <br /> <br />30 REMOTE SENSING SUPPORT <br /> <br />This program provides remote sensing support to other Recovery Program <br />investigations and changes annually to meet research needs. Work includes: anllUaI <br />collection and maintenance of aerial videography of the Green and Colorado Rivers; <br />acquisition of aerial video imagery; and preparation of color prints for selected reaches <br />along with interpreted results relating habitat to flow. Special requests for imagery and <br />imagery acquisition are accommodated when possible. Currently supported projects <br />are scheduled to conclude in FY 96. Video basemaps also are being developed to <br />begin putting data in a geographic information system, This project pfovides critical <br />data on relationships between flows and overall habitat availability within the Upper <br />Colorado River Basin. Quantified habitat values produced from this study will allow <br />biologists to evaluate and possibly enhance species monitoring (ISMP), and develop <br />baseline habitat and channel information, as well as monitor habitat change over time. <br /> <br />Recommendations: (I) We continue to recommend that a geographic information <br />system (GIS) be developed as a tool for integrating Recovery Program data. This is <br />being done for some of the razorback data. (2) Along these lines, we fecommend that <br />an all-inclusive list of available aerial imagery of the Upper Basin be compiled and made <br />available to all researchers. We are completing such a list for imagery that we have in <br />our possession. The following information is being included: (a) type of imagery, <br />(b) scale of imagery, (c) date of acquisition, and (d) area of coverage, preferably by <br />river mile. <br /> <br />32 FG!: SQUAWFISH REPRODUCTION & LARVAL ASSESSMENT <br /> <br />Larval Colorado squawfish were sampled with drift nets at three sites as they were <br />transported downstream from spawning areas located in the lower Green River near <br />Green River, Utah and in the lower Yampa River, Colorado in Echo Park, Dinosaur <br />National Monument. Sampling began in 1990 and will continue through 1996. Data <br />gathered provided a measure of annual reproductive success which was compared with <br />abundance data gathered on older life stages in other studies. Effects of various flow <br />and temperature regimes on reproduction by Colorado squawfish also will be assessed. <br />Specific objectives are to determine: I) timing and duration of spawning by Colorado <br /> <br />A-S <br />
