Description    


This proposed project complements the Warm Springs Tribe (WST) PCSRF #16-Warm-03 Log Springs Meadow Restoration I project. With the 2018 PCSRF funds, the WST will use some of the funds towards construction costs that werent covered under the 2016 project to remove or contour berms in the scoured channels (1.4 miles of stream reconfigured) to allow for connectivity with historic channels (2 miles of side channels accessed). The majority of the PCSRF funds will be used for a large native vegetation riparian planting effort within the meadow system which will treat two miles of riparian streambank and treat 100 riparian acres.



Coyote Creek is tributary to lower Beaver Creek (a tributary of the Warm Springs River) and is a significant contributor of stream flow during runoff periods. There are no fish present within the project area, Log Springs Meadow. However, the current environmental conditions within the area have contributed to poor downstream spawning conditions in Beaver Creek for Middle Columbia River ESU spring Chinook salmon and summer steelhead through excessive amounts of fine sediments entering from the Coyote Creek subwatershed, specifically the Log Springs Meadow area. Increases in fine sediment lead to greater substrate embeddedness and a decrease in interstitial spaces in gravel substrate important for salmonid spawning. Successful salmonid egg incubation requires clean gravels with low fine sediment content. The primary purpose of the project is to reduce erosion and delivery of fine sediments to important spawning and rearing habitats downstream in Beaver Creek.



The project area consists of a large open meadow and young, even-aged ponderosa pine trees in the uplands. There are three existing berms within the meadow. Only the “upper berm” and “lower berm” will be removed/contoured as part of this project; work on the “east berm” will be undertaken in the future; all other project elements will occur throughout the entirety of the meadow. The berms were installed about 40 years ago to control flow and sedimentation downstream of Coyote Creek. The berms and associated structures are showing signs of massive flanking and downstream erosion. Stream channels downstream of the berms are overly deepened, widened and disconnected from the floodplain. Stream channels show evidence of livestock damage: destroyed or reduced vegetation and trampled banks. All contributing factors have had adverse effects on the surrounding ecosystem, which is capable of producing food plants important to the Native American culture, such as camas and Lomatium spp.



Primary Project Objectives:

• Retain water within the meadow in order to enhance growing conditions for riparian vegetation and prolong stream discharge

• Elevate the water surface in order to activate a larger area and expand the wet meadow

• Decrease entrained fine sediments within the water column in order to reduce downstream sedimentation within spawning locations

• Reduce stream power

• Minimize streambank erosion

• Increase riparian vegetation abundance



Project Elements:

1. Install beaver dam analogs and vegetated channel swales, locations for these will be determined by using topographic survey and LIDAR

2. Remove or contour berms

3. Grade the floodplain in specific locations as designed

4. Slope vertical streambanks in specific locations as designed

5. Partition stream flows into existing channel scrolls throughout the meadow

6. Fill entrenched channel segments to desired elevations

7. Plant and seed the project area with locally sourced native vegetation

Project Benefit    


About 25% of the total amount of spring Chinook spawning and 20% of summer steelhead spawning occurs in Beaver Creek downstream of the confluence with Coyote Creek (project area, Log Springs, is in the upper watershed). A significant amount of fine sediment enters Beaver Creek during runoff from Coyote Creek. It is believed that the majority of the sediment is being produced within the project area and above. Thus, the primary expected benefit to target salmonid species in an overall reduction of streambed sedimentation downstream of the confluence, ultimately increasing emergence success and egg to fry survival of target salmonids.
