partners. For example, the Service is engaged in several major 

 restoration efforts in California, including the Klamath River 

 Basin, the Chehalis River Basin, and the Central Valley. The 

 Service, along with the Bureau of Reclamation, the National Park 

 Service, the U.S. Forest Service, and the Bureau of Land 

 Management is working cooperatively to determine the effects of 

 pulsed flows on the out-migration of fish in the Klamath Basin. 

 This information will be invaluable for future management 

 decisions. The Service is also nearing completion of a ten year 

 study assessing the flow needs of the Trinity River, a major 

 contributor to the Klamath Basin's salmon population. 

 Concurrently, the Service is pursuing development of a fishery 

 habitat restoration plan to be integrated with recommendations of 

 the flow study. 



Restoration activities in the Trinity and Klamath basins have 

 focused on stabilizing eroding streambanks, physically restoring 

 instream habitat (channel modification) , and adjusting stream 

 flows. Similar efforts are ongoing in the Chehalis River basin, 

 with special emphasis on improving water quality in the estuary. 

 Efforts in the Sacramento River and Central Valley focus on 

 improving water quality and quantity, improvements to physical 

 habitat, and use of hatchery technology to preserve the unique 

 genetic characteristics of the Sacramento River stocks.
