- Abstract:
- Construction work associated with a new spill basin bottom occurred during the evening hours (1600-0230 hrs) on 46 of the 61 days between 19 August and 18 October 2002 at Lower Monumental Dam. We monitored the movements of adult fall Chinook salmon Oncorhynchus tshawytscha and steelhead O. mykiss outfitted with radio transmitters and determined the time they used to make their first approach and first entrance at a monitored fishway opening, and their total time to pass the dam. We compared values from 2002, when construction occurred, with those from the preceding two years, prior to construction. We additionally compared the proportionate use by salmon and steelhead of the three available openings (orifice gates were closed in 2000-2002) to first approach and first enter the dam. We also examined proportionate use of the two fish ladders to pass the dam. All of these comparisons were made across the three years to evaluate any changes in adult fish behavior that may have been associated with construction activity.
