1. What is the geological process that is reducing the size of this lake? Estimate the acreage size of Rieck’s Lake now?
At one time Rieck's Lake was an open body of water over 80 acres in size.
By the early 1930s the open water of Rieck's Lake was reduced.
In the years since the completion of the dams on the Mississippi River , erosion has continued to fill Rieck's Lake . Gone is the watters of the lake. Without the submersed vegetation fewer tundra swan stop at Rieck's Lake during fall migration.
