Talbot Dam Removal Design

The work that was done under this grant resulted in final stamped designs for the removal of Talbot Dam and permit applications submitted. To get to the final designs survey work was conducted of the area. Multiple on site meetings were held to meet with stake holders. Including DNR, WDFW construction crew, and community members interested in the project. Designs were reviewed by WDFW biologist and DNR at increments of 30, 60 and 90%. Feed back was also gathered from the Willapa Bay Lead Entity on the design of the channel. All comments and suggestions were taken and incorporated into the design. Cultural Resources survey and report was completed by WDFW Archeologist. This work was done by working closely with DNR Archeologist to obtain information needed and ensure that all elements that needed to be were included in the report. A public meeting has been set with DNR to meet with the public and discuss the project. DNR wanted to wait until final designs were done before setting a meeting date.

The goal was met to complete final design for the restoration actions to remove a dam and address habitat diversity, channel stability and sediment loading to increase spawning and rearing habitat and open up fish passage for chum, coho and steelhead.
The design incorporated:
Installing 8 to 12 large woody debris jams over 1,000 meters in Green Creek to aid in sediment retention and sorting.
Installing 8 to 12 large woody debris jams over 1,000 meters in Green Creek to accumulate additional wood, promote scour and create cover for juvenile fish.
Plant riparian vegetation throughout the project reach to increase shade cover the stream and eventually be a source for wood recruitment.
Remove the 115 long and 20 tall earthen dam will allow for unimpeded movement of all life stages of all salmon throughout the year.
Restore the floodplain with the addition of woody debris. Woody debris and sediment retention to increase the interaction.
