FEATURED PROJECTS...
In 1996, Cramer Fish Sciences (CFS) implemented a juvenile salmonid out-migration
monitoring program at Caswell Memorial State Park on the lower Stanislaus River.
Operations by CFS have occurred annually at this site to estimate abundance of
out-migrating juvenile Chinook salmon and steelhead/rainbow trout in order to
understand the impacts of instream flow schedules and management actions.
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.
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).
 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.
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.
