(a) The General Assembly finds and recognizes that:
- (1) Illinois' 2,900 lakes and 82,000 ponds provide many economic and social benefits including fishing, swimming, boating, water supply, wildlife habitat, flood control, tourism, and property value enhancement; and that the public uses and benefits of Illinois' water resources are heavily concentrated on lakes;
- (2) in an assessment made by the Illinois Environmental Protection Agency in 1988, 86% of the number and 88% of the acreage of assessed lakes had impaired uses, caused primarily by nuisance growth of weeds and algae, turbidity, sedimentation or toxicants;
- (3) long-term improvements in the State's lake resources can be realized most effectively if comprehensive lake management strategies are implemented; and
- (4) implementation of these comprehensive strategies requires a careful analysis of the cause and effect relationships between lake impairments and the causal factors found both in the lake and in the lake's tributary watershed.
