ODFW AQUATIC INVENTORY PROJECT OREGON PLAN FOR SALMON & WATERSHEDS STREAM RESTORATION HABITAT REPORT STREAM: Wildcat Creek (NC-369) BASIN: Nestucca River SURVEY TYPE: Pre-Tx DATE: March 21, 2007 SURVEY CREW: Matthew Strickland, Sharon Tippery REPORT PREPARED BY: Paul Jacobsen BASIN AREA: 2.2 km2 USGS MAPS: Beaver ECOREGION: Coast Range Coastal Uplands GENERAL DESCRIPTION: The Wildcat Creek habitat survey extended 2,047 meters. The channel was constrained by terraces in a broad valley floor. The average valley width index was 7.4 (range: 1-20). Land use for the reach was young timber (3-15 cm dbh) and second growth timber (15-30 cm dbh). The average unit gradient was 3.0 percent. Riffles (52%) and rapids (35%) dominated stream habitat. Cobble (37%) and gravel (32%) dominated stream substrate. Wood volume was low at 11.5 m3/100m. COMMENTS: There were no potential barriers to upstream fish migration in the surveyed length. 4 culverts were documented. Minimal beaver activity and a Steelhead trout redd were noted in the survey.
