Abstract

Thermal stratification of five man-made lakes in southern Iowa are studied in relation to basin morphometry. The lakes were Red Haw Lake, Lacey-Keosauqua Lake, Green Valley Lake, Lake Keomah and Lake Darling. Form of the water mass was compared by three mathematical indices including basin slope, area development and volume development. Strongly stratified lakes had the greatest maximum and mean depth, basin slope, area development and volume development. Lakes with unstable and temporary stratification had lower values for basin configuration. Unstratified lakes had the lowest morphometric indices. The use of these indices for predicting the tendency for stratification of a basin prior to dam construction was discussed.
