The Pomme de Terre River begins cool and clear in Otter Tail County, bordered by wooded hills and grassy meadows. It flows south through several lakes; as the river nears its mouth, it is bordered by eroding banks, becoming increasingly muddy before discharging into the Minnesota River at Marsh Lake.

Designing stormwater systems to handle the challenges of climate change differs in every community across the state. Here’s how one community is meeting that challenge
The discharges in summer 2024 happened during the construction of the MnDOT truck facility in Eden Prairie, Minnesota.
For National Farmers Day, a profile of pork and crop farmer Randy Spronk of Edgerton, Minnesota, and his sustainable ag practices.
The MPCA's chloride reduction program assists communities and organizations across Minnesota in identifying sources of chloride.
Under the federal Clean Water Act, states must designate beneficial uses for all waters and develop water quality standards to protect each use.
Sustained efforts by cities and water management organizations have restored water quality in two Dakota County lakes.
The Minnesota Pollution Control Agency (MPCA)’s draft wastewater permit for the 3M facility at Cottage Grove adds new water quality protections for the Mississippi River and improves accountability through monitoring and reporting requirements. The draft permit is one of the most rigorous in state history and mandates the removal of certain per- and polyfluoroalkyl substances (PFAS) to levels below detection.
The MPCA is authorized to develop numeric water quality criteria that apply specifically to a water body or region where the pollutant is found, using data from that water body or region.
When temperatures climb, conditions are ripe for Minnesota lakes to produce algae blooms, some of which can be harmful to pets and humans.
The MPCA is proposing to amend Minnesota Rules governing animal feedlots.
Keep It Clean focuses on the growing problem of garbage and human waste left on the ice by anglers and other visitors during ice fishing season.
The MPCA added three bodies of water to the impaired waters list for PFAS contamination. Which are they? How did they get polluted? And how much PFAS does it take to contaminate a body of water?
The MPCA developed the Wastewater Nitrogen Reduction and Implementation Strategy to decrease the wastewater sector’s nitrogen loads for the protection and restoration of bodies of water in and downstream of Minnesota.
