Madison, Wisconsin: Wisconsin Department of Natural Resources
Summary
A statewide survey of the inland waters of Wisconsin was initiated in 1974 by the Bureau of Research, Wisconsin Department of Natural Resources (DNR) to establish a comprehensive data base on the distribution and relative abundance of all fish species. Records composing this data base came mainly from a survey between 1974 and 1986 of current statewide fish distribution. Numerous historical records (from 1900-72) were also included in the data base.
