Three year base-line assessment of sturgeon in Lake Roosevelt from Grand Coulee Dam to the international border, including the Spokane River arm on the Spokane Indian Reservation.
Project start year 1997 End year 1999
Start of operation and/or maintenance
Project development phase Planning
The Lake Roosevelt Monitoring / Data Collection Program (BPA No. 9404300) monitors and evaluates the effects of kokanee salmon and rainbow trout outplanting into Lake Roosevelt by the Spokane Tribal Hatchery (BPA No. 9104600), Sherman Creek Hatchery (BPA NO. 9501100), The Native Fish Stock Status (NPPC No. 10.8.B26) will provide information essential to the development of biological / integrated rule curves. Additionally, Canadian white sturgeon projects will be related to this project.
Biological results achieved
Annual reports and technical papers
Project will establish the status of white sturgeon in Lake Roosevelt. The sturgeon may warrant ESA protection.
Specific measureable objectives
Conduct an assessment of sturgeon in Lake Roosevelt including estimates of current populations size, abundance of each age class, age/length frequency, recruitment rate, natural and fishing mortalities, distribution patterns, harvest, life history, habitat usage, environmental factors effecting abundance and an assessment of the potential for artificial propagation.
The population of Lake Roosevelt white sturgeon is decreasing at an alarming rate.
Underlying assumptions or critical constraints
Lake Roosevelt white sturgeon will be sampled to determine the current population size, abundance of each age class, age/length frequency, recruitment rate, mortalities, distribution and migration patterns. Methods for sampling fish will follow those summarized by Stetter and Brannon.
Brief schedule of activities
The Lake Roosevelt Sturgeon project will begin in 1997 and continue through 1999. Continue white sturgeon population research including evaluating the development and maintenance of operations and facilities to enhance white sturgeon production by supplementation.
Data on Lake Roosevelt white sturgeon is sparse. Due to recent declines in catch and harvest rates attention must be given to this dwindling species, and action taken to ensure the survival of the Lake Roosevelt white sturgeon.
What is the white sturgeon status in Lake Roosevelt?
Summary of expected outcome
The Lake Roosevelt white sturgeon project will assess the current population of white sturgeon in Lake Roosevelt. Operation facilities to enhance white sturgeon production by supplementation for depressed populations in the impounded portions of the Columbia and Snake Rivers will be developed and maintained. Experimental white sturgeon research on contaminants, reproduction and genetics will be developed and maintained.
Dependencies/opportunities for cooperation
The Lake Roosevelt Monitoring / Data Collection Program (BPA No. 9404300) monitors and evaluates the effects of kokanee salmon and rainbow trout outplanting into Lake Roosevelt by the Spokane Tribal Hatchery (BPA No. 9104600), Sherman Creek Hatchery (BPA NO. 9501100), The Native Fish Stock Status (NPPC No. 10.8.B26) will provide information essential to the development of biological / integrated rule curves.
Without knowing the white sturgeon status, appropriate management plans are lacking. As a result the stock may be lost.
The Lake Roosevelt Hatchery Coordination Committee could be expanded to review work completed by this project.
