8 <br />site sampling on the Yampa River were made by electrofishing and <br />angling. Standardized sampling was not possible in the Lilly Park <br />area because launching sites for the electrofishing boat were made <br />hazardous or inaccessable by recent rains. The only alternative <br />method to collect squawfish was to use hook-and-line sampling from <br />a canoe in the Lily Park area. <br />1984 <br />In Yampa Canyon, fish collections were made with stationary <br />and floating trammel nets. Adult and juvenile fish were collected <br />on the upper Yampa River by boat electroshocking using-equipment <br />described by Wick et al. (1981,1985). Trammel nets were used for <br />stationary and moving (active) sampling within Yampa Canyon as <br />described by Wick et al. (1983,1985). Hook-and-line sampling was <br />conducted in the Lilly Park and Juniper Springs Canyon areas of the <br />Yampa River. <br />Habitat Monitoring 1984 <br />Habitat information was collected at all sampling locations and <br />included habitat type, depth, velocity, substrate, cover, and water <br />temperature. Three depth transects were recorded within the first <br />0.5 mile intensive site of each 5 mile section on the Colorado <br />River. On the Yampa River, maps were drawn of all special sites; <br />thalweg and cross-sectional depth chart recordings were taken in a <br />1 mile section at each site. Habitat types were categorized by <br />depth and counted within each special site. Preliminary habitat <br />analysis was conducted in Yampa Canyon by identifying on maps and <br />photographing all suspected spawning areas. <br />A Lowrance model LRG-1510B sonar depth recorder was used to <br />record depths at transects, and a Marsh-McBirney model 201
