| Its that time of year again where you could really have a bummer trip if you hit a lake during the flip,,not to mention people thinking about driving hundreds of miles and making lodging reservations to a certain lake,,anybody care to keep an update of 'pending turover or the actual flip" please list ANY and all from around the state
Minnetonka has of sat 9-23 59-61

| fisher!!!
here is a great way to learn about 'turnover"-Right from the Minn DNR
go to the web address posted below and page down till you hit the section on turnover,,alot of other good stuff in there too

Location: MPLS, MN | Has Tonka really started to turn already? Or it's about to. I always thought the turnover was about 55 |

| shallow back bays on Mantrap around Cobb's island were turning over last week.
water temps at 56, water churned up, colored, and lots of floating crap.
the west arm was still clear, and the main east lake basin was good, with temps there at 63. |

|
| Sunday 9/24 White Bear was 61 and very, very murky pretty much everywhere but there was no floating debris. Seems a bit early and with the heavy rains hard to tell for sure but it looks like it's starting. Hopefully it's over and recovered before the full moon period. |

| I think he meant it doesn't thermocline - you can bet the big pond surface temps are higher than 20' down - "turnover" is misunderstood by most but there is a lot of information on internet, books, ect if you want to understand thermocline, turnover , ect |

Location: Musky Tackle Online, MN | B420 is correct, Mille Lacs doesn't turnover. Big wide open lakes such as Mille Lacs that aren't very deep don't have turnover. A big wind constantly mixes the water out there. That's why you can get several calm hot days in the summer and see water temps in the low 80s. Get a big wind and the water temps drop significantly even if the air temps are still in the 90s. The entire water column gets mixed.
Leech Lake is another example like this. Although on Leech it's just the main lake. The bays out there will go through turnover.

| lakes turnover. Some dont thermocline:
Lakes "turnover" in the fall and spring . . .
Water density varies with water temperature. Water is most dense (heaviest) at 39 degrees Fahrenheit (4C) and as temperature increases or decreases from 39 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 39 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.

Not Mille Lacs. Mille Lacs is a "polymictic" lake, meaning that it mixes several times a year, when the wind blows. Technically, you could say it turns over, but not in the same way of other lakes because it has nothing to do with the water temperature. I've scuba dived in Mille Lacs several times and when the wind blows, there is no difference in temp, even in 30 ft water. Even when it is calm and hot, only the very top layer of water is wamer.
Do a search, there was a discussion of this last year. You could also email one of the DNR limnologists about Mille Lacs because it is a very unique lake and usually discussions about turnover and thermoclines relate to typical lakes.

Like muskyslayer posted, not all lakes turnover, Mill Lacs is one, Winnebago, are 2 good examples, not all lakes establish statified thermocline like you are talking about. Look at PWT in August. catching walleye in 3 feet.

| when fisherman think of turnover they are typically talking about a Dimictic lake.....thats why I simply corrected the earlier statement of turnover...mille lacs rarely develops a thermocline for any extended period so fall turnover is less pronounced....
.....you are right in saying that Mille Lacs is Polymictic (its actually a Cold Polymictic Lake -it freezes) but your incorrect in saying it does not turnover - It turnsover often during the summer-thats why its Polymictic -when surface temps are 84 its not 84 30' down. turnover after iceout..yes...why?...because Mille Lacs is water...this can happen quickly because of wind.
Mille Lacs is a Holomictic lake (Holomictic lakes circulate throughout the entire water column at some time during the calendar year.
Amictic lakes are permanently ice-covered and do not ever turnover

think about this part of the amazing world we live in: what would happen if water was at it's most dense or heaviest at 32 degrees??? doh. |

| Does Turnover move fish deeper ? If the big pond dosent turn then is it the cisco that cause the fish to move? How do rivers play into turnover ? |

| White Bear was 60 on Sunday. I don't think it's turned yet. Anybody know a good rule of thumb for what temp turnover happens? I thought it was around 55.

| turnover doesn't necessarily happen all at once. I think it's been going on for almost 2 weeks on WB. The water is greener than I have every seen it and there's lots of fish real shallow. With temps currently "stabilized" near 60 I'm guessing there's still be a bit more turning going on once we get some colder temps. |

Location: Maple Grove, MN | I don't know about Tonka. The water temps were between 60 and 62 yesterday and we covered much of the lake.
It seems Tonka is stuck in a pre-turnover or partial turnover phase. The water temps seem to be just a little to warm to get the water mixing well enough to complete the turnover process. Of course, turnover can start and stop with warming water so that might be what is going on. A little mixing here. A little mixing there. Just not enough to get it over with.
Whatever it is, the fish were turned off like a light switch.
It might be best to try another lake this weekend. Anything going on Indy?  |
