The Mississippi River will be the first of the state's five largest rivers to be monitored for water quality as part of the Minnesota Pollution Control Agency's watershed monitoring program. The other large rivers that will be monitored in the coming years are the Minnesota, Rainy, Red, and St. Croix.
The large river monitoring will provide data to assess the aquatic life, aquatic recreation, and aquatic consumption designated uses in the main stems of these rivers. This large river monitoring will complement the M-P-C-A's ongoing assessment of smaller streams, rivers, and lakes throughout Minnesota's 81 major watersheds.
More information on this monitoring effort can be found on the Minnesota Pollution Control Agency's website.
