Effect of Water Level Fluctuations on Abundance of Young-of-year Largemouth Bass in a Hydropower Reservoir
Trends in the abundance of young-of-year largemouth bass (Micropterus salmoides) and water level fluctuations from 1976 to 1988 in Grand Lake were evaluated to assess recruitment strength before (1976-1981) and after (1982-1988) a change in reservoir operations. Significantly positive relationships between abundance of young-of- year largemouth bass and days of littoral flooding during spawning and nursery seasons, drawdown during revegetation season in the previous calendar year, combinations thereof, and water levels during these seasons indicated recruitment of largemouth bass was...
