Hydroacoustic Assessment of Downstream Migrating Salmonids at Lower Monumental Dam in Spring, 1985 Final Report.
- BioSonics, Inc., Seattle, WA
The primary objective of this study was to estimate the effectiveness of the spillway in passing migrants, with the spillway operating per the criteria identified in the COE's 1985 Juvenile Fish Passage Plan. Specific study objectives were to estimate: (1) the effectiveness of the spillway for Passing migrants; (2) die1 variability in passage rates of migrants through the powerhouse and the spillway; (3) the daily and cumulative run timing of migrant passage; (4) the proportions of migrants that passed through each turbine intake and spill bay (i.e., the horizontal distributions across the powerhouse and the spillway); and (5) the vertical distributions of migrants approaching the powerhouse and spillway.
