STREAM REPORT

STREAM: Little North Fork Wilson River LLID: 1237387454728 BASIN: Wilson River HUC NUMBER: 17100203 SURVEY DATES: February 7-10, 2011 USGS MAPS: The Peninsula, Cedar Butte ECOREGION: Coast Range Volcanic WATERSHED AREA: 51.2km2 FIRST ORDER TRIBUTARIES: 33 STREAM ORDER: 3 SURVEY CREW: Jon Frech and Kimberley Beedle REPORT PREPARED BY: Peggy Kavanagh and Sharon Tippery GENERAL DESCRIPTION: The Little North Fork Wilson River habitat survey began at its confluence with the Wilson River and

ended 5,167 meters upstream at the confluence of White Creek. Five reaches were designated based on tributary influence and land use changes. The land uses were second-growth timber

(15-30cm dbh), large timber (30-50cm dbh), mature timber (50-90cm dbh), and old growth trees (90+cm dbh). The surveyed habitat was mostly riffles and scour pools. Cobble and gravel substrates were most commonly recorded. Hardwoods and conifers 3-15cm dbh were found most frequently in the riparian zone. GPS readings were in NAD 83.

REACH DESCRIPTIONS: Reach 1 - (T01S-R09W-S24NW) – 550 meters – The first reach of the Little North Fork Wilson River habitat

survey began at its confluence. The channel was constrained by hillslopes in a narrow valley. The valley width index was 1.0. There were 50 meters of secondary channel habitat. The land uses were large timber and second-growth timber. The average gradient was 0.6 percent. Riffles (44%), scour pools (28%), and glides (20%) were the predominant stream habitats. Gravel (41%) was the primary stream substrate. Wood volume was 13.6m3/100m. No riparian transects were conducted in this reach.

Reach 2 - (T01S-R09W-S13SW) - 1312 meters – Reach 2 was designated when the crew corrected a

survey collection technique and ended at a tributary junction. The channel was constrained in a narrow valley. The average valley width index was 1.8 (range: 1.5-2.0). The average gradient was 0.8 percent. The land uses were large timber and second-growth timber. Riffle (52%) and scour pool (31%) comprised the majority of the stream habitat. The primary substrates were gravel (32%) and cobble (34%). Wood volume was 12.0m3/100m. The trees found most frequently in the riparian zone were 3-15cm dbh hardwoods. Total number of trees per 100m2: 2.0 conifers and 3.7 hardwoods (based on 1 riparian transect).

Reach 3 - (T01S-R09W-S13NW) – 1933 meters – Reach 3 extended from a tributary junction to another tributary. The channel was constrained by hillslopes in a narrow valley. The average valley width index was 1.5 (range: 1.0-2.0). The land uses were large timber and second-growth timber. The average gradient was 0.7 percent. Scour pools (45%) and riffles (35%) dominated the stream habitat. The substrate was a mix of gravel (22%), cobble (26%), boulder (23%), and bedrock (17%). Wood volume was 26.7m3/100m. The trees found most frequently in the riparian zone were conifers 3-15cm dbh. Total number of trees per 100m2: 4.0 conifers and 1.0 hardwoods (based on 2 riparian transects).

Reach 4 - (T01S-R09W-S12SW) - 550 meters – Reach 4 spanned tributary junctions. The channel was

constrained in a narrow valley. The valley width index was 1.0. There were 89 meters of secondary channel. The average gradient was 1.2 percent. The land uses were large timber and mature timber. The stream habitat was primarily scour pool (36%), riffle (29%), and rapid (27%). The substrate was mainly gravel (22%), cobble (27%), and boulder (30%). Wood volume was 75.2m3/100m. The trees found most frequently in the riparian zone were 3-90cm dbh conifers. Total number of trees per 100m2: 1.7 conifers and 0.0 hardwoods (based on 1 riparian transect).

Reach 5 - (T01S-R09W-S12NE) – 822 meters – Reach 5 began at a tributary junction and ended at the

confluence of White Creek. The channel was constrained by hillslopes in a narrow valley. The valley width index was 1.5. The land uses were mature timber and old growth trees. The average gradient was 1.0 percent. Rapids (54%) and scour pools (39%) dominated the stream habitat. Boulder (25%), cobble (26%), and gravel (21%) were the primary stream substrates. Wood volume was 37.5m3/100m. There were no riparian transects in this reach.

COMMENTS: The last fish was observed at unit 82 (3418m). A fish presence / absence survey was not

conducted. An ODFW Life Cycle Monitoring screw trap was located at unit 17 (550m).

Chinook and coho salmon carcasses and live adults were noted. Beaver-chewed sticks were seen throughout the survey.

A portion of Reach 3 had young trees (<15cm dbh) and conifers 15cm dbh. This section spanned

~800 meters of the ~1900 meter reach.
