This report presents the 1974 to 1977 results of a study undertaken on the site of the Columbia Electric Generating Station to determine the effects of leakage from the cooling lake on wetland vegetation. Results showed that changes in water levels and water temperatures caused by seepage from the cooling lake led to significant changes in wetland plant populations and communities within 1 yr after the Columbia Station began operation. Dominant perennial rhizomatous species of Carex decreased in density and distribution, hydrophytic species increased, and annual species increased markedly. A predominant trend of decreasing species diversity and richness was observed from 1974 to 1977. However, no uniform relationship was observed between diversity and intensity of disturbance--neither species richness nor distribution of their abundances.
