Snake River - St. Croix Basin

Watershed at a Glance

The Snake River begins about 6 miles north of McGrath, in the Solana State Forest in southern Aitkin County. It flows 90 miles southward and then eastward, and about 560 feet down to the St. Croix River east of Pine City. The Snake River and its tributaries drain about 986 square miles of watershed.

Land use ranges from largely agricultural and urban in the south to largely forest and wetland in the north.

What's being done

There is currently one sub-watershed TMDL complete (Groundhouse River for bacteria and biota), and one currently underway for the Ann River subwatershed for biota, bacteria, and excess nutrients.  

Work for the watershed study started in the spring of 2010 with monitoring of 4 lakes and multiple stream sites. The plan is to continue monitoring for one more year, and then start the modeling work in the winter of 2011. After that, work will start with local partners to develop a protection plan for the unimpaired water bodies.
