DESCRIPTION
The problem is 2 fish passage barrier culverts on Camp Creek on separate road
crossings on Schafer Boom Road southeast of Montesano, Washington. These barriers
are:
Site 1: WDFW Site ID 127S0362. 46.9801/-123.56473. 0.16 miles south of Schafer
Boom/Simmons Rd. junction. 33% passable. Rip rap is present at both the culvert
inlet and outlet Rip rap at the outlet creates large scour pool. The barrier consists of
a round corrugated steel pipe, 3' in diameter, 30' long, not countersunk, with a slope
of 2.2%. Slope is reason for barrier determination. The stream has a 20' bankfull
width. The site is at stream mile 0.42.
Site 2: WDFW Site ID 127S0361. 46.98121/-123.56489. 0.10 miles south of Schafer
Boom/Simmons Rd. junction. The barrier culvert is a round corrugated steel pipe 3'
in diameter and 36' long. High velocities create a 67% passable barrier. The site is at
stream mile 0.55.
This restoration project is to correct 2 fish passage barrier culverts on Camp Creek on separate road crossings on Schafer Boom Road southeast of Montesano, Washington: Site 1: WDFW Site ID 127S0362, lat/long 46.9801/-123.56473, located at road mile 0.16 on Schafer Boom Road, it is 33% passable. Rip rap is present at culvert inlet and outlet. Rip rap at the outlet creates a large scour pool. This barrier consists of a round corrugated steel pipe, 3' in diameter, 30' long, not countersunk, with a slope of 2.2%. The stream has a 20' bankfull width. The site is at stream mile 0.42. This correction has been designed and permitted under SRFB Grant 16-1327; this portion of the project is for construction of the previously-designed correction. Designs are attached.Site 2: WDFW Site ID 127S0361, lat/long 46.98121/-123.56489, located at road mile 0.10 on Schafer Boom Road. The barrier culvert is a round corrugated steel pipe 3' wide and 36' long. High velocities create a 67% passable barrier. The site is at stream mile 0.55. Objectives and tasks include design and permitting of this barrier correction, so no designs are attached. The overall goal is to improve fish passage to 10.21 miles of high quality upstream habitat for 5 species of salmonids: Chinook, coho and chum salmon, steelhead and cutthroat trout. Site 2 is 0.13 miles upstream from Site 1. 1.26 miles of good quality spawning and rearing habitat will free of barriers after both blockages are corrected.
