Measuring Stream Baseflow Conditions in West-Central Wisconsin

Abstract

This study seeks to measure baseflow conditions in West-Central Wisconsin to aid in determining the impacts of groundwater withdrawals on local streams. Streamflow is measured monthly at fifteen (15) sites across eleven (11) streams during baseflow conditions using an OTT MF ProWater Flow Meter. Baseflow conditions are determined by referencing recent rainfall totals and the USGS streamflow gage records. Streams with two or more sites are used to determine if streams are gaining or losing water. A stream gage and seasonal pressure transducer has been installed at one site (18-Mile Creek at County Highway A) to establish a relationship between the stream’s stage and discharge. This study is conducted by the University of Wisconsin-Eau Claire in partnership with the Water Use Section at the Wisconsin Department of Natural Resources.
