ODFW AQUATIC INVENTORY PROJECT STREAM REPORT STREAM: East Fork Green River BASIN: Alsea Basin DATES: August 19-20, 2003 SURVEY CREW: Mark Stone and Kip Wood REPORT PREPARED BY: Sarah Beldin STREAM ORDER: 3 BASIN AREA: 7.1 km 2 FIRST ORDER TRIBUTARIES: 9 USGS MAPS: Herman Creek ECOREGION: Coast Range-Sedimentary HUC NUMBER: 17100205 LLID: 1238300442480 GENERAL DESCRIPTION: The East Fork Green River habitat survey began at the confluence with Green River and extended 1,970 meters. Two reaches were designated based primarily on channel morphology and substrate type. The surveyed area was predominantly constrained by alternating high terraces and hillslopes. Land use was dominated by mature and second growth timber. Trees in the riparian zone were dominated by 3-50cm dbh hardwoods. Scour pools (51%) and riffles (30%) were the dominant habitat types. Dominant substrate types were gravel (37%) and cobble (29%). Average unit gradient was less than 1%. Stream temperatures recorded during the survey ranged from 13.0- 16.0 o C. REACH DESCRIPTIONS: Reach 1: (T15S-R09W-S19SW) Reach 1 began at the confluence with Green River and extended 891 meters. The stream channel was predominantly constrained by alternating high terraces and hillslopes in a broad valley. The valley width index was 5.8 (range: 3.5-9). Land surrounding the area contained mature (50-90cm dbh) and second growth (15-30cm dbh) timber. Stream habitat was dominated by scour pools (55%) and riffles (25%). Stream substrate was comprised primarily of gravel (39%) and cobble (24%). The average residual pool depth was 0.46m. Trees in the riparian zone were dominated by 30-50cm dbh hardwoods and 90cm + dbh conifers (based on 2 transects). The average unit gradient was 0.5%. Wood volume was 75m 3 /100m primary channel length. The crew noted actively eroding and undercut banks along 15% and 17% of the reach length, respectively.

STREAM REPORT

STREAM: East Fork Green River BASIN: Alsea Basin DATES: August 19-20, 2003 SURVEY CREW: Mark Stone and Kip Wood REPORT PREPARED BY: Sarah Beldin STREAM ORDER: 3 BASIN AREA: 7.1 km2 FIRST ORDER TRIBUTARIES: 9 USGS MAPS: Herman Creek ECOREGION: Coast Range-Sedimentary HUC NUMBER: 17100205 LLID: 1238300442480 GENERAL DESCRIPTION: The East Fork Green River habitat survey began at the confluence with Green

River and extended 1,970 meters. Two reaches were designated based primarily on channel morphology and substrate type. The surveyed area was predominantly constrained by alternating high terraces and hillslopes. Land use was dominated by mature and second growth timber. Trees in the riparian zone were dominated by 3-50cm dbh hardwoods. Scour pools (51%) and riffles (30%) were the dominant habitat types. Dominant substrate types were gravel (37%) and cobble (29%). Average unit gradient was less than 1%. Stream temperatures recorded during the survey ranged from 13.0-16.0oC.

REACH DESCRIPTIONS:

Reach 1: (T15S-R09W-S19SW) Reach 1 began at the confluence with Green River and

extended 891 meters. The stream channel was predominantly constrained by alternating high terraces and hillslopes in a broad valley. The valley width index was 5.8 (range: 3.5-9). Land surrounding the area contained mature (50-90cm dbh) and second growth (15-30cm dbh) timber. Stream habitat was dominated by scour pools (55%) and riffles (25%). Stream substrate was comprised primarily of gravel (39%) and cobble (24%). The average residual pool depth was 0.46m. Trees in the riparian zone were dominated by 30-50cm dbh hardwoods and 90cm + dbh conifers (based on 2 transects). The average unit gradient was 0.5%. Wood volume was 75m3/100m primary channel length. The crew noted actively eroding and undercut banks along 15% and 17% of the reach length, respectively.

East Fork Green River con’t Reach 2: (T15S-R09W-S30NW) Reach 2 began at the end of reach 1 and extended

1,079 meters. The stream channel was predominantly constrained by alternating high terraces and hillslopes in a broad valley. The valley width index was 5.9 (range: 4-8). Land surrounding the area contained mature (50-90cm dbh) and second growth (15-30cm dbh) timber. Stream habitat consisted primarily of scour pools (47%) and riffles (35%). Stream substrate was dominated by gravel (36%) and cobble (33%). Trees in the riparian zone were dominated by 3-30cm dbh hardwoods. The average residual pool depth was 0.51m. The average unit gradient was 0.9%. Wood volume was 48.3m3/100m primary channel length. The crew noted actively eroding and under cut banks along 12% and 25% of the reach length, respectively.

COMMENTS:

The crew observed Coho fry as well as debris jams throughout the surveyed length.

The crew noted beaver activity throughout reach 1 and habitat structures

throughout the surveyed length.
