Two reaches were designated based on tributary contribution. The land uses were light grazing, heavy grazing, and agriculture. The surveyed habitat was primarily glides with hardpan clay, fine sediment, or gravel substrate. Hardwoods 3-15cm dbh and grass were found most frequently in the riparian zone. REACH DESCRIPTIONS: Reach 1 - (T01S-R38E-S24NW) – 3,994 meters – The first reach of the Willow Creek habitat survey began at a property boundary and extended to the Coon Creek confluence. The channel was constrained by high terraces within a broad valley. The valley width index was 20.0. The average gradient was 0.1 percent. The land uses were heavy grazing and agriculture. Glides (88%) dominated the stream habitat. Hardpan clay (63%) and fine sediment (26%) were the primary stream substrates. Eleven percent of the reach length had active erosion. There was one piece of countable wood in the reach. The trees found most frequently in the riparian zone were 3-15cm dbh hardwoods (based on 6 riparian transects). Grass was the primary component of the riparian zone transects. Reach 2 - (T01S-R38E-S14NW) - 870 meters – Reach 2 started at the Coon Creek confluence and ended at the confluences of Fir and Dry Creeks. The channel was constrained by high terraces in a broad valley with a valley width index of 20.0. The average gradient was 0.4 percent. The land uses were light grazing and agriculture. The stream habitat was a mix of scour pool (35%), riffle (31%), and glide (34%). The substrate was a mix of fine sediment (18%), gravel (49%), and hardpan clay (26%). There were two pieces of countable large woody debris. The trees found most frequently in the riparian zone were 3-15cm dbh hardwoods (based on 3 riparian transects). Grass was the primary component of the riparian zone transects.

STREAM: Willow Creek LLID: 1179324454921 BASIN: Grande Ronde River HUC NUMBER: 17060104 SURVEY DATE: September 13 and 15, 2010 ECOREGION: Blue Mountain Basin and Upland USGS MAP: Summerville WATERSHED AREA: 54km2 FIRST ORDER TRIBUTARIES: 78 STREAM ORDER: 4 SURVEY CREW: Jesse Steele and Ryan Lande REPORT PREPARED BY: Peggy Kavanagh and Jesse Steele GENERAL DESCRIPTION: The Willow Creek habitat survey began at a property boundary and ended ~4.8 kilometers upstream
at a tributary junction. Two reaches were designated based on tributary contribution. The land uses were light grazing, heavy grazing, and agriculture. The surveyed habitat was primarily glides with hardpan clay, fine sediment, or gravel substrate. Hardwoods 3-15cm dbh and grass were found most frequently in the riparian zone.
REACH DESCRIPTIONS: Reach 1 - (T01S-R38E-S24NW) – 3,994 meters – The first reach of the Willow Creek habitat survey began
at a property boundary and extended to the Coon Creek confluence. The channel was constrained by high terraces within a broad valley. The valley width index was 20.0. The average gradient was 0.1 percent. The land uses were heavy grazing and agriculture. Glides (88%) dominated the stream habitat. Hardpan clay (63%) and fine sediment (26%) were the primary stream substrates. Eleven percent of the reach length had active erosion. There was one piece of countable wood in the reach. The trees found most frequently in the riparian zone were 3-15cm dbh hardwoods (based on 6 riparian transects). Grass was the primary component of the riparian zone transects.
Reach 2 - (T01S-R38E-S14NW) - 870 meters – Reach 2 started at the Coon Creek confluence and ended at
the confluences of Fir and Dry Creeks. The channel was constrained by high terraces in a broad valley with a valley width index of 20.0. The average gradient was 0.4 percent. The land uses were light grazing and agriculture. The stream habitat was a mix of scour pool (35%), riffle (31%), and glide (34%). The substrate was a mix of fine sediment (18%), gravel (49%), and hardpan clay (26%). There were two pieces of countable large woody debris. The trees found most frequently in the riparian zone were 3-15cm dbh hardwoods (based on 3 riparian transects). Grass was the primary component of the riparian zone transects.
COMMENTS: The last fish (sculpin) was observed at unit 35 (2744m). A fish presence / absence survey was not
conducted. Hardpan clay was present throughout the stream and was represented as bedrock. There was a screened diversion at unit 8 (503m).
