Description    


The Nora Creek Meadow Restoration Project is located on Nora Creek, tributary to Little Bear Creek in the Potlatch watershed. The goals of the project were to restore meadow hydrology and riparian vegetation to address low summer baseflow and temperature, which are limiting factors for steelhead in the Potlatch watershed. To meet these goals, Latah SWCD removed flow from 0.64 miles of straightened and incised channel and reconstructed 0.86 miles of main (0.77 mi) and side channels (0.09 mi) in the historic alignment. Twenty-four acres of floodplain were reconnected through this project. Fifteen structures (logs fastened together and Beaver Dam Analogs (recorded as ‘other engineered structures’ in metrics)) were placed in the newly reconstructed channel to create habitat, slow flow and add channel complexity. Two of these structures (BDAs) were installed later as part of an adaptive management strategy- one to eliminate a potential head cut and one to further slow flow and trap sediment in the lower portion of the project area. Fifteen pools are expected to be created through scour. Channel diversion structures and ditch plugs were placed in the disconnected stream channel to divert the flow, prevent recapture of the flow in the incised ditch, and to create a series of wetland cells. These and three constructed persuasion channels were revegetated with sedge mats, native grass and forb seed, cuttings, and container plants. Berm removal, fill areas, wetland swale construction, riparian revegetation efforts, invasive weed control and slash placement further enhanced the habitat and stability of the project site. Post-project photo monitoring indicates that enhanced floodplain access was achieved, and that the riparian revegetation process has begun.

A contract extension for this project allowed for additional plantings through the 2020 planting season.

On January 23, 2019, Latah SWCD partnered with Alta Science and Engineering on a poster presentation at the River Restoration Northwest annual conference in Skamania, Washington. A pdf of the poster is attached to the final report.

Notes on metrics: Wetland metrics and levee removal were not included in the proposed metrics. Values for these have been included in the actual metrics to record these actions.

Project Benefit    


This project will implement four of five priority actions identified in the NMFS October 2016 proposed recovery plan for the Lower Mainstem Clearwater River steelhead population of the Clearwater MPG, Snake River steelhead ESU in a priority watershed (Potlatch River). The proposed actions include the following:

1. Restore hydrologic processes to retain surface flow by reducing surface runoff from altered land surfaces, disconnecting artificial drainage systems from natural drainage systems, and modifying water uses. This will contribute to reducing stream temperature problems.
2. Restore channel-forming processes by reestablishing floodplains in incised channels, removing or setting back flood control structures, and rehabilitating stream channels that have been straightened.
3. Reestablish riparian vegetation to improve LWD recruitment and create shade for streams.
4. Reduce fine sediment delivery to streams where it is increased caused by agriculture, road drainage systems (including undersized culverts), or other artificial sources.
