The MEC has an extensive <br />library of fishery reports from the CDOW that date back to the late 1970s. These reports <br />include the population studies on the Fryingpan and Roaring Fork rivers. We have a <br />copy of 1989 environmental assessment for the Fryingpan -Arkansas Project and used <br />the literature cited section in that document as one resource to identify pertinent historical <br />studies. <br />2001 Results <br />The draft report was completed in 2001 and submitted to the Roaring Fork Conservancy. <br />We are waiting to receive one additional report from the Bureau of Reclamation before <br />completing the final report. <br />The literature review and in particular, the fish population data, will be used in the <br />analysis of flow-habitat relationships and flow-population relationships if possible. <br />Instream Flow Study <br />Methods <br />We are conducting an IFIM study to evaluate the relation between flow level and trout <br />habitat. The IFIM requires hydraulic and habitat suitability data to determine the <br />instream flow requirements for the species of interest. The preferred method of hydraulic <br />simulations is a single velocity IFG4 model (Milhous 1984). This method requires at <br />least one full set of hydraulic measurements (bed profile, velocity profile, water surface <br />elevations and discharge) and preferably several stage-discharge measurements. <br />Draft 2001 Task Summary Report Page 3 <br />Miller Ecological Consultants, Inc.
