Description    


This project targets recovery of the Toppenish Creek population of the Yakima Basin major population group of middle Columbia steelhead. We propose to restore full fish passage at two box culverts, restore aquatic habitat in 0.4 miles of existing channel using large wood structures, re-wet 1,600 feet of side channel that is currently dry due to channel incision, restore flow and sediment transport continuity by installing a new bridge, create alcove habitat in 3 small inset floodplain areas, treat two headcuts using designed riffles to maintain channel grade, and revegetate 5 acres of riparian and upland vegetation.

Project outcomes will be increased quality and quantity of instream habitat in a documented spawning and rearing reach for middle Columbia steelhead, full fish passage up and downstream, and improved stream processes of flood conveyance, floodplain and side channel engagement, and sediment transport.

The total project cost is $1,196,637. PCSRF funds ($96,637) will pay for a portion of the logs and root wads needed for the large wood structures. Other funds will pay for design, the remaining materials, and construction.

Worksite #1 Proposed Work: Simcoe Creek, River Mile 10.5
We propose to address the following limiting factors using the methods described as follows. 1) Impaired aquatic habitat: Increase quality and quantity of available aquatic habitat by installing large wood structures and adding riffles and pools and creating 5 seasonally wetted and 1 flood-event activated side channel, all located in historic channel pathways. Create alcove rearing habitat at the outlets of 3 of the side channels. Maximize duration of wetted channel conditions during dry season via consolidating low or base-flow conditions into single channel. Improve shade and nutrient contributions by creating floodplain benches that can support riparian vegetation. PCSRF funding will be used to purchase a portion of the logs with rootwads needed for the large wood structures. Other funds will pay for the remaining materials and actions. 2) Impaired fish passage: Install bridge with fish-passable roughened riffle next to existing box culvert under W.White Swan Road. Convert existing east box culvert into an over-flow flood route with fish-passable roughened apron up and downstream. Construct roughened apron downstream of existing west box-culvert crossing under W. White Swan Rd to improve downstream migration flood flow hydraulics. These actions will be paid for by non-PCSRF funds. 3) Active Incision: Reduce risk and impact of continued incision (vertical and lateral) through construction of designed riffles in the mainstem that provide grade control. Create opportunities via installation of large wood structures and side channel creation for inset floodplains. Create opportunities for development of inset floodplain and increased channel sinuosity via installation of Large Wood to produce hydraulic roughness and flow deflection. PCSRF funding will be used to purchase a portion of the logs with rootwads needed for the large wood structures. Other funds will pay for the remaining materials and actions. 4) Disconnected floodplain: Create narrow floodplain benches that will be inundated during 1.5-year flood event and slightly set-back existing vertical banks to increase available floodplain. Increase frequency and area of historical flood inundated by creating seasonally activated side channels. These actions will be paid for by non-PCSRF funds. 5) Lack of Riparian Zone: Improve riparian zone vegetation by planting native seed and live plants in areas created to support and maintain riparian vegetation such as the created floodplain benches, slightly laid-back vertical banks, and reactivated historical flow routes through the floodplain. Build 0.4 miles of fencing to protect stream riparian area from grazing, and add a fenced livestock crossing (water gap). These actions will be paid for by non-PCSRF funds.

Project Benefit    


The proposed project will result in two major benefits to the Toppenish Creek steelhead population. First, full passage will be restored in a spawning and rearing reach of Simcoe Creek, the major tributary of Toppenish Creek. There are 20 miles of spawning habitat upstream of the project site with no known passage barriers, resulting in a significant gain in access to spawning grounds for returning adults. In addition, this project restores full downstream passage to juvenile fish out-migrating in the spring. Second, the project restores complexity and cover to 0.4 miles of main channel and creates 1,600 feet of off-channel habitat in an area of highly degraded habitat, which should enhance spawning and rearing opportunities, in addition to providing increased high-flow refuges. A secondary benefit is the treatment of active headcuts which will conserve existing spawning and rearing habitat upstream of the project area.
