Chewuch River 8 Mile Ranch Project
The 8 Mile Ranch Project (8 Mile Ranch) restores habitat and hydraulic refuge for fish rearing and holding within one reach of the Chewuch River. The work performed provides fish habitat, stream complexity and restores a functional riparian zone in an area currently without any vegetation.
Branch Creek Armored Stream Crossing
Branch Creek enters North Fork Toppenish Creek at river mile 3.2, and drains a 23-square-mile watershed. Mid-Columbia River steelhead use the stream for spawning and rearing. Two locations on Branch Creek were identified as suitable for culvert removal and replacement by armored stream fords. One is located at RM 1.1 and the other at RM 1.4. The project is located in the NW1/4, NE1/4, Township 9 North, Range 14 East, Section 1, on tribal trust land in the closed area of the Yakama Reservation.
Sunnyslope Side Channel
The Sunnyslope Side Channel Project is located on the Wenatchee River at RM (river mile) 1.4. This excavated side channel is approximately 1,350 feet in length. It is connected to a natural side channel of the Wenatchee River at the upstream end and flows into the mainstem of the Wenatchee River at the downstream end. This project is aimed at creating a groundwater fed side channel with an upstream connection during high flows (approximately 7,000 cfs or greater).
Toppenish Ridge Stockwell & Pipeline
This project was implemented to assist in managing the migration of cattle from low elevations in the spring to higher elevations in the early summer. Prior to the project, upon cattle turnout on May 1, cattle would quickly travel approximately 25 miles to the headwater meadows of Satus and Toppenish Creeks. Livestock immediately impacted several important high elevation meadows, by overgrazing and by creating hardened cattle trails. These impacts further increased channel incision and bank erosion in these areas..
Lincoln Meadows Restoration
Lincoln Meadows is a headwaters meadow for Toppenish Creek. Headwater meadows are important because they contain culturally important first foods and function as water storage to maintain summer base flows in streams, which supports aquatic life. Lincoln Meadows has been impacted by a variety of human related activities, such as roads and cattle grazing, that have severely degraded the meadow's capabilities.
Panther Creek Passage Barrier Removal
On August 6, 2011, Yakama Nation Fisheries, Yakama Reservation Watersheds Project (YRWP) completed the implementation of a restoration action at two road/stream interfaces on Panther Creek to improve stream function and facilitate fish movement. Sites within the Panther Creek watershed have been degraded due to various human activities (e.g., grazing, road building, and logging). These problems are most obvious at the site on Panther Creek where Fort Simcoe Road # 80 transects T10N, R13E Section 13 and further downstream in T10N, R13E Section 26.
LaSalle High School Fish Habitat Improvement & Floodplain Enhancement
Yakama Reservation Watersheds Project staff completed a bank stabilization and floodplain restoration project in and adjacent to Ahtanum Creek. Anthropogenic and natural factors have led to the rapid erosion of three stream meanders, a discontinuity between the floodplain and the stream, and a domination of non-native invasive vegetation within the project site. Endangered Species Act listed species: Mid-Columbia River steelhead trout and bull trout, Chinook, and coho; utilize Ahtanum Creek for multiple life history stages.
