Short description
Adult fish passage can be sensitive to spill discharge and the patterns of that discharge. There is need to continue to assess the effectiveness of adult spill patterns in terms of providing appropriate passage conditions to minimize passage delays. An ancillary concern to adult passage spill patterns is the sensitivity of different patterns on the production of DGS.

Management implications
Information will provide the opportunity to utilize optimal spill patterns to reduce passage delay across a range of spill discharge levels.

Specific measureable objectives

Testable hypothesis
B.2.6. Spill patterns cannot be adjusted to optimize passage conditions for adult salmon.

Underlying assumptions or critical constraints
Field testing is dependent on a range of spill conditions and the operational flexibility to vary conditions. Field testing of alternative spill patterns may be dependent on hydraulic modeling at the Corpsí Waterways Experiment Station.


Brief schedule of activities

Biological need
Adult passage can be sensitive to hydraulic conditions created by spill. Spill discharge patterns are needed for both voluntary (fish spill) as well as involuntary spill conditions. In both cases, we need to ensure the most appropriate discharge patterns are used to minimize negative effects on adult passage, or in some cases, as a means to enhance adult passage.

Critical uncertainties

Summary of expected outcome
Field validated optimal spill patterns for adult fish passage across a range of spill discharge levels.

Dependencies/opportunities for cooperation


Monitoring activity
Evaluation of the effectiveness of spill patterns would be primarily through radio-tracking of adult passage at dams under the ongoing adult passage evaluation study by UI/NMFS.

Section 3. Budget

Data shown are the total of expense and capital obligations by fiscal year. Obligations for any given year may not equal actual expenditures or accruals within the year, due to carryover, pre-funding, capitalization and difference between operating year and BPA fiscal year.
