I though I would post this to help get a good mind set going into the open water season.

Minnesota has 48 native mussel species, of these 25 are endangered, threatened, or of special concern. http://www.dnr.state.mn.us/mussels/index.html . To put this in to light we must look back. In the early 1900’s we had less agriculture run off and less storm drains pouring water into the lakes. Water was clearer back then. The bivalves were in there environment. Over the year we have changed that environment to one that some of the bivalves cannot adjust to and die off in some of our lakes. Without the presence of these bivalves the water is not strained and is no longer clear.

This makes some of our lakes powder kegs just waiting for the introduction of a bivalve that can put up with the way our lakes are now. Inter the Zebra Mussels, the conditions in some of our lakes are primed and ready for them.
