Merced River Ranch Floodplain Restoration In 2008, Cramer Fish Sciences began working with the U.S. Fish and Wildlife Service Anadromous Fish Restoration Program and the California Department of Fish and Game on the Merced River Ranch Floodplain Restoration Project. The Merced River Ranch was purchased by CDFG in 1998 for the purpose of protecting riparian habitat, improving conditions for salmonids, and providing a long-term source of gravel for the Merced River and nearby projects. The site is located just below Crocker-Huffman Dam in the Dredger Tailings Reach of the Merced River. This area was heavily impacted by gold mining during the turn of the century and is the southernmost extent of Chinook salmon populations. The vision of the project is to restore ecosystem processes and critical habitats for juvenile and adult salmonids, in coordination with local communities and stakeholders, to promote the recovery of healthy and diverse Chinook salmon and steelhead populations in the Merced River.

Out-migration Monitoring In 1996, Cramer Fish Sciences (CFS) implemented a juvenile salmonid out-migration monitoring program at Caswell Memorial State Park on the lower Stanislaus River. We have continued to estimate abundance of out-migrating juvenile Chinook salmon and steelhead/rainbow trout at this site each year in order to distinguish the effects of instream flow schedules and management actions.

Watershed Population Support Analysis Identifying how many fish a stream can support is a critical factor when managing watersheds. Clients such as Portland General Electric and the Bonneville Power Administration face these challenges and Cramer Fish Sciences provides the answers by using it's own Unit Characteristic Method (UCM).

Dam Flow Effects Cramer Fish Sciences was hired by the Kennewick Irrigation District and U.S. Bureau of Reclamation (USBR) to estimate the effects of flow alternatives below the Prosser Dam on the Lower Yakima River in Washington. The goal was to quantify the potential benefits to salmon of the various flow alternatives being considered. PIT tag (passive integrated transponder) data was used from spring Chinook, fall Chinook, and coho salmon juveniles as well as other data to show the effects different flow scenarios had on salmonid survival.

Fish Population Recovery Plan The Lower Columbia River Recovery Board relied on Cramer Fish Sciences to lead the effort in developing, coordinating, and drafting a comprehensive Recovery Plan for salmon and steelhead populations in the Lower Columbia River Basin. Click here to read more...
Life-Cycle Modeling A comprehensive analysis of population dynamics of coho salmon throughout the Klamath River basin is needed to distinguish the separate effects of Reclamation flow management from other limiting factors affecting coho. It was determined that a life-cycle model was the appropriate analysis tool for this purpose. Click here to read more...
