Abstract:

Low flow criteria need to be developed for determining the suitability of various low flow regimens for fish and wildlife. For choosing a desirable low flow release, the decision maker needs to know the increase in cost of a reservoir to provide a low flow release, for a range of low flows. Investigations and analyses are carried out to develop information on fish suitability or preference for different flow releases and the associated incremental costs of potential reservoirs at 123 gaging stations on streams in Illinois.
