Zumbro River Watershed - Turbidity: TMDL Project

Minnesota's Impaired Waters and TMDLs


The Zumbro River Watershed TMDL includes thirteen listings for turbidity. The majority of turbidity listings were added to the 2006 303(d) Impaired Waters List as a result of analysis of Citizen Stream Monitoring Program (CSMP) transparency data. To complete this project, the MPCA has contracted with Barr Engineering Inc, an environmental engineering firm. The Zumbro Watershed Partnership has also been involved in this project. Field work and data collection are currently underway.
