Have any of the lakes in the area turned over? I'm especially interested in Clearwater. I didn't think it was cold long enough up there, but wind usually helps and I know you had some of that!
I will be up there on the 29th and I hope the lakes don't turn over when I'm there.
Also how are the water levels?

I haven't heard of any turnover in the Metro area... maybe someone else could chime in for other parts of the state.

Some of our small lakes have started the process, around here
and some of the lakes are way up from the rains, but it has
been cold for about a week with a couple days of snow, soon it
will be time to get out the short poles. Chris

I'm not sure, but can someone give me a few ideas on how to figure out if it has or not? I would like to check BSL this weekend.
Thanks, cool smiley

The biggest clue is just a drastic change in water temps. The reports I have been seeing for the area still have most lakes in the mid to high 60's. The magic number I have heard is about 50 degrees.
When they turn over they will take about a 10 to 20 degree drop in a short period of time. The other clue is the water color will turn darker because of algae, silt and decaying mater. This could also be caused by rain and or wave action from high winds which usually help to turn over a lake.

Here is a good article I found on the subject.

What is meant by "lake turnover"? How and why do lakes do this in autumn and spring?

  • The key to this question is how water density varies with water temperature. Water is most dense (heaviest) at 39º F (4º C) and as temperature increases or decreases from 39º F, it becomes increasingly less dense (lighter). In summer and winter, lakes are maintained by climate in what is called a stratified condition. Less dense water is at the surface and more dense water is near the bottom.
  • During late summer and autumn, air temperatures cool the surface water causing its density to increase. The heavier water sinks, forcing the lighter, less dense water to the surface. This continues until the water temperature at all depths reaches approximately 39º F. Because there is very little difference in density at this stage, the waters are easily mixed by the wind. The sinking action and mixing of the water by the wind results in the exchange of surface and bottom waters which is called "turnover."
  • During spring, the process reverses itself. This time ice melts, and surface waters warm and sink until the water temperature at all depths reaches approximately 39º F. The sinking combined with wind mixing causes spring "turnover."
  • This describes the general principle; however, other factors (including climate and lake depth variations) can cause certain lakes to act differently. A more detailed description of the physical characteristics of lakes, including temporal and density interactions, can be found at the Water on the Web site, sponsored by the University of Minnesota - Duluth and funded by the National Science Foundation.

    I have just got off a metro lake and the water temp was 51, Today is Tuesday the 23rd. No
    they have not turned over yet. The first thing you will notice is the smell. It smells like garbage only worse. I bet they will turn over for Metro lakes in the next week or so.
    After turnover give it a rest for 6-8 days then hit them hard. The Bass will hit spinner baits, swim baits and crank baits.
    Now is the time to catch the bigest Bass of the year.

    Bass Wishes,
    Mike
