Zumbro River Load Monitoring Network
The Olmsted County Soil and Water Conservation District will assist the Minnesota Pollution Control Agency (MPCA) with water quality monitoring and pollutant load calculations at four sub-watershed sites in the Zumbro River Watershed. Approximately 25 grab samples per site between ice-out and October 31 of 2019 will be collected along with field measurements and observations. Samples will be collected using procedures described in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance (SOPG). QA/QC samples will also be collected and are included as a part of the sample count. Sites include: North Fork Zumbro River (near Mazeppa, MN), Middle Fork Zumbro River (near Oronoco, MN), South Branch Middle Fork River (near Oronoco, MN) and South Fork Zumbro River (near Rochester, MN). Seasonal load calculations for each site will be calculated using the FLUX32 model.
