Whether fed by rivers, streams or underground springs, lakes collect everything rain washes down from the surrounding watershed. Today, these fragile ecosystems are feeling the effects of runoff from asphalt, automobile emissions, septic wastes, fertilizers, household cleaners and other pollutants. In its natural state, a lake can support many different kinds of plants and animals. Insects, crustaceans and fish hide among tangled plants in a tree-lined shore. Insects and fish spawn in rocky shores or gravel beds close to shore. And cold, clear, clean water provides the healthiest environment both for aquatic life and for people. |
