Stevens Point Flowage Bathymetric Survey and Mapping Project

Project Abstract

The Stevens Point Flowage Bathymetric Survey and Mapping Project is a cooperative partnership between the UWSP GIS Center and local non-profit organizations, local governments, businesses, and individuals. In 2013, GIS Center students and faculty completed a 2,800 acre bathymetric survey that documents flowage depths. Over 120,000 data points were collected over a period of 13-discontinuous days on the water. Students and faculty donated over 200 hours conducting the survey and crafting the map. Thank you to our community partners and friends for supporting the printing and distribution of over 5,000 flowage maps to the public. We hope you agree that this map is a functional resource for using and enjoying the Stevens Point Flowage of the Wisconsin River - the nation’s hardest working river.
