STREAM REPORT STREAM: McCoy Creek Tributary A1 BASIN: Donner and Blitzen DATES: August 9, 2005 SURVEY CREW: Tom Stassen and Nicole Judge REPORT PREPARED BY: S. Stein STREAM ORDER: 2 BASIN AREA: 3.4km2 FIRST ORDER TRIBUTARIES: 1 USGS MAPS: Wildhorse Lake ECOREGION: High Desert HUC NUMBER: 17120003 LLID: none GENERAL DESCRIPTION: (T32S-R33E-S34NW) The McCoy Creek Tributary A1 habitat survey began at the confluence with
McCoy Creek Tributary A and continued upstream 1,144 meters. The channel was bedrock-constrained in a moderate v-shaped valley floor. The average valley width index was 2.4 (range: 1.2-5.0). Land uses for the reach were wilderness area and light grazing. The average unit gradient was 7.1 percent. Cascades (43%), scour pools (28%), and rapids (23%) were the dominant stream habitats. Bedrock (34%), cobble (23%), gravel (21%), and boulder (19%) comprised most of the primary stream substrate. No large wood debris was recorded in the reach. The average residual pool depth was 0.31m. The trees found most frequently in the riparian zones were hardwoods 3-15cm (based on four riparian transects).
COMMENTS The crew observed trout. There is a 1.6m bedrock step at unit 11 (88 meters) that was a potential
barrier to upstream fish migration. The upper fish distribution was not determined.
There were many spring seeps entering the stream. Cattle activity was noted in the upper length of the reach.
