“The Rat-Marsh River Watershed is located in southeastern Manitoba. The two main rivers in the watershed are the Rat River and the Marsh River. The Rat River begins in the Sandilands Provincial Forest near the town of Carrick and flows west and northwest to the downstream confluence with the Red River about three kilometres north of Ste Agathe. The two main tributaries of the Rat River are the Joubert Creek and Sand River. The Marsh River begins approximately fifteen kilometers southeast of Morris and flows north through the Red River Valley joining the Rat River near Ste. Agathe.

The Rat-Marsh River Integrated Management Plan is now approved by the Minister of Conservation & Water Stewardship. Please take a look and let us know what you think!

An Integrated Watershed Management Plan, or’ IWMP’, is like a roadmap for your watershed team and other stakeholders. Integrated watershed planning and management is defined as a process to promote the coordinated development and management of water, land and related resources on a watershed basis. Check out our Seine River IWMP!

Manitoba’s Water Protection Act was proclaimed in January of 2006. This Act provides the basis for launching and financing the integrated watershed management planning initiative.
