. ~ III. Study Goals, Objectives, End Product A. Goals: I. To describe the physical habitats that currently exist in the Gunnison River upstream from Redlands Diversion. Z. To quantify year-round flows that will maintain and enhance Colorado squawfish and razorback sucker habitat in the Gunnison Riyer upstream from Redlands Diversion. B. Objectives: 1. To quantify relationships between habitat and streamflow -- particularly that between peak discharge and flooded, quiet water areas. Z. Use aerial video techniques, ground-truth data and other measurements made on the water, and existing habitat-use information to describe the availability of important habitats in the Gunnison River. 3. Begin the process to develop year-round flow recommendations for the Gunnison River. 4.' Use aerial-video to describe channel morphology of Gunnison ,River at base flow. Provide baseline information to detect changes in channel morphology over time. 5. Identify areas that may be appropriate for habitat improvement projects. IV. Study Area (river miles and sampling dates, if appropriate) Gunnison River, Redlands Diversion Dam to Delta, Colorado (River Mile Z.5 to 55) V. Study Methods/Approach Aerial photography and aerial videography will be combined with ground truthing to describe the available habitats in the Gunnison River and their relationship 'with streamflow. The study will be a multi-year study. Color infrared aerial photography will be acquired during a base flow period that also includes vegetation in full leaf. The optimum time to acquire both of these variables is in October. This will allow for the development of a base map with a minimum water component and maximum vegetation. The photography will be flown at an approximate scale of I:IZ,OOO with a 30% side lap and a 60% forward lap. Photography will include a I kilometer buffer on both sides of the river. 2
