The silt bottomed prairie lakes of Clay and Palo Alto Counties, Iowa, have shallow, hard, alkaline, turbid waters. They are located in the youngest of the glacial drifts, in which the soils are highly calcareous and rich in mineral salts. The more shallow lakes with relatively flat, saucer-like basins, support a rich population of rooted, submerged, and emergent vegetation which minimizes wave action. The lakes whose basins are deeper than four feet are unfavorable to the growth of emergent vegetation and rooted submerged types do not survive the wave action except in the shallow waters along the depositing shores.
