In order to better manage populations of lakes and streams it is useful to have some form of lake and stream classification. In biological monitoring programs, an appropriate geographic framework is useful for developing estimates of organisms likely to be collected and conditions likely to be encountered. As assemblage and water quality data bases and statistical software have become available, they have been used to frame regions. Others have compared aquatic ecosystem patterns with various environmental variables. The purpose of the paper is to compare fish faunal regions and ecoregions, summarize the experience of two states that use ecoregions as management units, and summarize the concerns of workshop participants about the use of ecoregions.
