Two Prairie Pothole Lakes

  1. They look like pretty good sized lakes. Out here we have some "pothole" or "kettle" ponds, but they're much smaller.

    1. Ed, some of these lakes are good sized, but one can alway see across them. There are many of these lakes in eastern SD. Most of them have a sizable fish population, pan fish, northerns, and walleye.

  2. Not heard the term pothole lakes before - were they created as a result of mining/quarrying?

    1. Hi Gerald, no, pothole lakes, aka Kettle lakes, are formed by receding glaciers. Huge blocks of ice fall off the face of a glacier, makes a depression, and fills it with melt water. In the east these lakes are seldom more than two kilometers across, but in the Midwest they can be up to 13 kilometers wide. Some of these lakes are fed by springs or are at water table hight, others must survive on precipitation. These lakes are 10-13 thousand years old.

  3. I like! I've never heard of the term, either, except in a profane reference while driving my car...

    Pan fish, northerns and walleye sound good!!!

    1. There may be carp in some of these lakes too. Some people like to eat them. The other fish are excellent eating, especially in the spring and early summer when the water is still cold. But I'm not really a fisherman. Get my fish at the grocery store.

      See my answer to Gerald for the origin of pothole lakes.
