The Lake Michigan Cooling Water Intake Technical Committee concluded from its study of Lake Michigan intakes that in view of the wide range of ecological situations encountered when siting Lake Michigan intakes, no generic type intake structure or system can be recommended. However, it is essential that a systematic approach be used in evaluating each site. Current intake structure technology limits the minimization of environmental damage to the protection of adult and immature fish, important to Lake Michigan. Intake siting is the most important factor in avoiding intake problems. Site determination and intake design, including flow velocity and mechanical equipment considerations, should be preceded by a monitoring program.
