Location of the three study sites for the Yampa River, Lily Park, Sevens and <br />Duffy. <br /> <br />The Cross Mountain Ranch is the landowner for most of the river at Sevens and <br />Lily Park. The BLM is the primary landowner at Duffy. In general, each site on the <br />Yampa River has distinctly different fish and habitat characteristics. Duffy is located in <br />Little Yampa Canyon and has some deep pools with large boulders that provide cover. <br />Duffy is low gradient. The primary habitat during the base-flow period consists of <br />shallow pools. Sevens is also low gradient with gravel-sand substrate. At typical base <br />flows, shallow, low-velocity pools and runs are the most common habitats. The Lily <br />Park site is higher gradient with a cobble-boulder substrate. Faster flowing habitats (runs <br />and riffles) dominate in Lily Park. The Lily Park site was added because of its better <br />native fish composition than at Duffy. <br /> <br />5 <br />
