This project will collect water samples at seventeen monitoring locations ranging in size from 23,173 acres (7 Mile Creek) to over 9 million acres (Minnesota River at St. Peter) as a part of the Watershed Pollutant Load Monitoring Network (WPLMN). The Minnesota State University - Water Resources Center (WRC) has been directly involved with the program and is familiar with the streams and hydrology of the region. In addition to monitoring, the WRC will review, manage and submit the data in formats provided by the Minnesota Pollution Control Agency (MPCA).
