1 ODFW AQUATIC INVENTORY PROJECT OREGON PLAN FOR SALMON & WATERSHEDS STREAM RESTORATION HABITAT REPORT STREAM: BASIN: SURVEY TYPE: South Sister Creek (U-5) Smith River Pre-Tx DATE: January 7, 4 SURVEY CREW: REPORT PREPARED BY: Michael Scheu, Jeremiah Bernier Paul Jacobsen BASIN AREA: 3.6 km USGS MAPS: ECOREGION: Gunter Coast Range Sedimentary GENERAL DESCRIPTION: The South Sister Creek habitat survey extended,45 meters. The channel was constrained by terraces in a broad valley floor. The average valley width index was 5.5 (range: 3.-8.). Land use for the reach was large (3-5 cm dbh) and second growth (15-3 cm dbh) trees. The average unit gradient was 1.4 percent. Riffles (36%) and scour pools (3%) dominated stream habitat. Bedrock (66%) dominated stream substrate. Wood volume was low at 5.6 m 3 /1m. COMMENTS: There were no potential barriers to upstream fish migration in the surveyed length.
