<br />efforts win be made for mapping fish distribution and abundance. Fish maps (polygons) will <br /> <br />be made so that meso-habitat suitability can be determined in each ofthe study sites. <br /> <br />CONCLUSIONS and RECOMMENDTATlONS <br /> <br />. Large differences were found in habitat and species composition between Duffy on the <br />Yampa River and Com Lake in the 15-Mile reach of the Colorado River. <br /> <br />. It is believed that the fishery is near the physical habitat carrying capacity in the 15-Mile <br />Reach and in the Dolores River, but predation is impacting density on the Yampa River. <br /> <br />. The 2-D flow modeling clearly produces excellent habitat mapping results and is <br />absolutely necessary for this project to develop instream flow recommendations for the <br />Yampa and Colorado Rivers. Stewart (2000) summarizes the 2-D modeling work <br />completed at this time. <br /> <br />. A contract to continue 2-D modeling was not approved in 2000 resulting in a one-year <br />delay in making instream flow recommendations for the Colorado River and the Yampa. <br /> <br />. Attempts to start a new contract are in process. An RFP (Request for Proposal) was <br />announced in an open competitive bidding and the RFP was awarded to a contractor. At <br />this time approval for the contract has not be give by DNR, but anticipate that it will be so <br />that work can resume in July I, 2001. <br /> <br />. Radio telemetry work will continue in 2001 given approval to contract the field work via a <br />purchase order. The telemetry work completed so far provide valuable data on habitat use <br />and movement of blue head sucker, flannel mouth sucker and roundtail chub. <br /> <br />ACKNOWLEDGEMENTS <br /> <br />The hydraulic modeling was contracted with Colorado State University, the <br /> <br />Department of Earth Resources. The contract was administered and supervised by Dr. Ellen <br /> <br />W ohl and Greg Stewart performed the work for a M. S. project. Greg supervised the habitat <br /> <br />quantification portion in the field and performed the hydraulic modeling. I greatly <br /> <br />appreciated the enthusiasm and energy Greg put into this study and the long hours he spent <br /> <br />setting up the technical equipment and calibrating the SMS model.
