Abstract
The Sangamon River, a small river in the central part of Illinois, has special interest to students of aquatic biology because it exhibits in a remarkable way the effects of the installation of a sewage treatment plant in alleviating pollution and at the same time the effects of the erection of a dam to impound water for munici))al and industrial uses. The present study is an attempt to determine to what extent these effects are reflected by changes in the abundance of certain kinds of microscopic organisms, collectively called ]5lankton, which live suspended in the water. As is well known, some kinds of plankton organisms, if present in sufficient numbers in reservoirs, may give diagreeable flavors to the water ; other kinds may aid in the natural purification of polluted waters: and in streams and lakes generally plankton plays a role of more or less importance as food for larger organisms, including fishes.
