The Rum River Watershed covers 997,060 acres in east-central Minnesota, covering parts of Aitkin, Crow Wing, Morrison, Mille Lacs, Kanabec, Benton, Isanti, Chisago, Sherburne, and Anoka counties.
Regular people are pretty good at judging water quality, and new research from the Minnesota Pollution Control Agency (MPCA) proves it.
When temperatures climb and the summer sun beats down, conditions are ripe for Minnesota lakes to produce harmful algae blooms, some of which can be harmful to pets and humans.

What is the blue-green scum that looks like spilled paint?In lakes that are over-enriched with phosphorus and nitrogen, algae tend to prosper and create algae blooms. Blue-green algae and one type in…
Four watershed scientists had an article published in LakeLine magazine. They report on 20 years of success getting lakes cleaned up.
Controlling phosphorus is an important part of protecting Minnesota waters.
Sustained efforts by cities and water management organizations have restored water quality in two Dakota County lakes.
The MPCA regulates most aspects of livestock management including the location, design, construction, operation, and management of feedlots and manure-handling facilities.
The Shell Rock River begins at Albert Lea Lake in Freeborn County in south-central Minnesota, a few miles from the Iowa border. It flows 113 miles into Iowa, where it enters the Cedar River. In Minnesota, the Shell Rock drains 246 square miles (160,000 acres), all in Freeborn County.
From shorter winter ice seasons to shifting fish populations, climate change is transforming Minnesota lakes as we know them.
Lake of the Woods is a big lake with a big problem caused by one of nature’s smallest organisms: algae. Scientists from the MPCA and the Science Museum are working together to understand why.

The Minnesota Nutrient Reduction Strategy (NRS) compiles the latest science, research, and data and recommends the most effective strategies to reduce nutrients in our waters from both point and nonpoint sources.
Improving water quality in Lake George has required treating phosphorus in the water and filtering pollutants out of urban stormwater.
When leaves fall on streets, sidewalks, and other hardscapes in urban areas, they wash into the storm drains and end up in lakes and rivers where they feed algae growth. The algae then decomposes and uses up oxygen that fish and native plants need.
