Abstract
The purpose of this study was to attempt to document any changes that may have occured due to the construction of a pump storage reservoir at Lake Charleston. The age I white crappie present in the new reservoir were observed to exhibit an increase in first year growth in 1982. This increase was observed in subsequent years but not to the same degree as was observed initially. The age II fish present in the new reservoir in 1982 exhibited a very large increase in growth for the first year of the new impoundment. In the years after 1982 the annual growth of age II crappie returned to essentially pre-construction levels. The large initial increase in size of age II fish is believed to be related to a very large gizzard shad spawn in 1982. The slow growth of white crappie in the years after 1982 is believed to be related to a lack of adequate forage for white crappie.
