The Grande Ronde Model Watershed Program (GRMWP) is the primary entity coordinating habitat restoration on both private and public lands within the Grande Ronde Basin. The Grande Ronde Basin covers approximately 5,300 square miles, containing more than 2600 miles of fish bearing streams, in the Blue Mountains of northeast Oregon. Snake River spring chinook salmon, summer steelhead and bull trout, which are listed under the Endangered Species Act, are present in the basin. The GRMWP began coordinating restoration projects in 1994. Approximately 215 projects have been implemented through the GRMWP program as of 1998. Nine of these projects were funded in part through the Bonneville Power Administration's 1998 Columbia Basin Fish and Wildlife Program. These nine projects used a variety of methods to enhance and restore watershed conditions. In-stream work to improve fish habitat included construction of hard structures (eg. vortex rock weirs), placement of large woody material and whole trees, gravel bar treatments, and improvements to off-channel rearing habitat; 55 miles of stream were treated. Fish passage was improved at three locations by replacing or removing culverts that blocked fish. Stream riparian conditions were enhanced with exclosure fencing, vegetation planting and thinning, noxious weed control, and floodplain enhancements; 10 miles of stream were directly benefited with these riparian improvements. Four spring developments were constructed to enhance riparian and stream conditions by providing off stream livestock water sources. Nine spring developments and 1 reservoir were improved with fencing and/or piping to troughs to reduce sediment runoff and restore riparian habitat. Roads were closed or obliterated (8.5 miles) and road drainage was improved (3.4 miles) to reduce sediment delivery to streams. These nine projects cost approximately 1.3 million dollars to implement and monitor. BPA provided 41% of the funding, the remainder was cost shared by county, state, and federal agencies, private landowners, Indian tribes and natural resource interest groups.
