Fall Turnover??

10 posts in this topic

Can anyone tell me if Mille Lacs experiences a fall turnover?? I know some lakes don't experience one for some reason....whatever that may be. I don't know much about that. But if it does have one, what time of year does it usually fall around? Thanks for any info. and help.

Mille Lacs has a turn over. No one can predict this time of year when it is going to occur.

During the summer months the lake surface temps are warmer than the bottom of the lake temps. The turn over occurs when the cool air of late fall/winter turns the waters surface temp colder than the temp at the bottom. Once this occurs the ice sheeting is soon to come. In a sense, the lake flips up side down. Its all derived upon temperature. This effects all aspects of a lake. The Thermo cline (hope I said correct word) level determines what a lake is going to do. Some lakes do not turn over, these are the lakes the have very thin ice during even the coldest winters or ice all year round (like in the actic).

This is what I have learned about the lake turning over! Could be wrong, but it fits the discription.

Excellent, but when does turnover occur?

October, November, ????????????

Actually, Mille Lacs is a polymyctic lake, in that it turns over, or mixes, many times throughout the year. Because it's a shallow, wind-swept lake, Mille Lacs doesn't usually have a chance to develop a strong temperature stratification like other lakes. Because of the weak stratification, a windy day will in a sense "turn over" or mix the temperature layers.

Some years you may notice a turnover effect in the fall and other years you really won't. As to when it happens in the fall if it happens at all.... confused.gif Turnover can be predicted but not this far out in advance. A turnover due to cooling surface temperatures will occur when the top layer of water denser than the water below and water is most dense at 4 degrees Celsius (39.2 F) so I would look for the effects of a turnover, if they happen at all, when the surface temps start getting into the lower 40s. Sorry, it's tough to pinpoint a specific time as I've fished open water on Mille Lacs in December and ice fished in November.

All good info. guys. Thanks for chiming in. I would imagine fall turnover to happen on Mille Lacs around the late october time period then, if it has a pronounced one that is???? From the description you gave me, I usually see my water temp. readings hovering around that low 40's mark in Later October. I am heading up in late September once and possibly once after fall turnover in November (that is if there isn't ice blocking the landings). Of all the areas to fish in Mille Lacs, what would be your first choice for fall fishing.....rocks, sand and gravel, or mudflats?? I have done well in the rocky areas of the southeast portion, but I do like exploring new territory. Any thoughts?

The turn over occurs most times in late Oct. to early Nov., but could easily occur in late Nov. to early Dec... Let’s hope we do not see late Dec.

The tullibie spawn is usually at the start of or during the turn over. If you shine your spot lights up on a shallow rock reef and see tullibie swarming, the turn over is close or has started.

There is no turnover on Mille Lacs.

Too shallow and windswept.

Willy,

I am talking in a weather/environmental sense, not a thermocline flip. The fact of Mille Lacs having a very low thermocline level and like you stated shallow and wind swept says the lake will not have a thermocline flip over(rare). Like I said in my first post, what I have come to learn as the Mille Laces turn over is basically a change in surface to bottom temps, not a thermocline rearrangement.

Like it was said before me, there is hardly ever a turnover on a Mille Lacs type lake. These lakes do not stratify during the summer thus no big temperature difference from top to bottom. It does even out however at 39 degrees so it will never be in December.

Well Mille Lacs doesn't Turnover... We shouldn't call what it does "Turnover" It's more like Mixing...

And as far as I know, this enigmatic "Hot Bite of Fall" isn't something that even predictable for that big lake.

      We survived our trip!  LOL   Fishing was steady.   We caught 30 walleyes in 3 days of fishing.  Usually fished from 11 am to 4 pm.  The 'eyes were running small, lots of 11 to 13 3/4" fish, but we did get 3 keepers.  We also kept a few nice perch and crappies.  We also caught a few snake northerns.   Jigging w/ chubs produced the best, but I did catch a few 'eyes on the crawler lindy rig combo.  Mid lake structure and underwater points off of islands all produced fish.  Mayflys were hatching, but the fish were still hungry. I did catch a 4-5 lb channel cat in the Savanna River one evening.   We stayed in the south loop of the Army Corp campground.  We liked that we were w/in about 30 yds of our boat which we kept at the dock.  The river on the north side of us and the lake on the south side offered a nice breeze to keep things cool and the bugs away for the most part.  Con's were the campsites are small and were too close together.  Also no turn around at the end of the south loop road.  The north loop was beautiful, spacious campsites, but surrounded by swamp and we heard the skeeters were bad at dusk.  Definitely want some thermacells or a screen tent to enjoy the evening by the sounds of things.  Also the docks aren't close/in view of the campsites.   We would definitely stay there again, on the north loop, in May or Sept. after the skeeters have died down a bit.   Staff was friendly, shower houses were nice, boat landings were nice.     Brian

      Went out Thursday for a few hours. Caught a 28" Walleye along with a handful of nice sized Bass.

      Just got back from our 34th annual Grand Marais trip. Weather, and how bad it was, was the theme. At one point or another, it rained every single day we were there! The wind was miserable he last couple days as well. Really affected our fishing plans, as we had to cancel out on some of our normal lakes, and fish some less than desirable backup lakes.   As per tradition, we left in the middle of the night and pulled up to the Lester River just a few minutes before sunrise. Didn't catch anything there. Also got skunked at the Talmadge and French rivers. I got free admission at Tom's logging camp on account it was Father's Day  and as always, kids had fun feeding the animals. I did catch a few little rainbows out of sucker, knife, and Stewart rivers. Had our traditional "fisherman's breakfast" at McDonalds in Two Harbors. We stopped at the silver creek tunnel, and that was the first time I've been at the overlook since it was actually part of the highway back in '94. We rolled into Grand Marais at about 3:30 and had to wait out a rain storm before putting the boat out on Kimball Lake. We lost several trout, and in the end, only my 6 year old son caught 2 rainbows.   Monday we fished Greenwood Lake, and as was the case with my 2 older kids, my 3 year old daughter caught her very first fish here...a smallmouth bass! Between all of us, we caught about 130 bass, all of which were pretty small. Unfortunately no lake trout. However, a big surprise occurred...while casting for bass, I caught a herring! Then a few minutes later, my son caught one also! Never would have guessed I'd ever catch one in the summer, let alone 2!   Fished a "secret lake" on Tuesday and caught quite a few northerns. They were all either 5 pounds, or 6 inches long, nothing in between. My son caught an 8 pound, 33 incher, which ended up being the biggest fish of the trip. We was screaming, and excited, and wanted me to take his fishing pole. But after about 10 minutes he finally got it in so I could net it. He's still bragging about it. My 3 year old also caught her 2nd ever fish, a perch, which ended up being the only one of the trip.   Went up to Saganaga on Wednesday. I spent I don't know how many hours trying to catch lake trout, but didn't find any!  Finally gave up and ventured deep into red rock bay for the first time ever. Really nice back there, wish I would've went there first. Fishing was ok, considering the weather was starting to get bad. Caught the biggest bass of the trip, a hair over 18 inches. On the drive back we seen a bear. Ironically it was walking down the road to black bear lodge at Poplar Lake.   Biggest disappointment came on Thursday. The plan was to fish both Hungry Jack and West Bearskin lakes. The wind was terrible, and coming straight from the west. Had hungry jack not had the reputation as a big bass producer, I wouldn't have went here. Unfortunately the big bass weren't around, nor any bass for that matter. Only caught 4 small bass. Kids caught about a dozen or so sunnies from the dock at the resort, some of which were decent size. We didn't even bother with bearskin. There's no way we would be able to launch our boats in that wind. We went to Loon Lake instead. In the limited time we were there, we caught about 30 tiny bass. My 9 year old daughter also caught her first rock bass. I tried for lakers, and marked a lot of them, but didn't catch any.    So since we didn't fish West Bearskin as planned, we penciled it in for Friday. Knowing the weather was going to be bad, we picked Poplar Lake as our backup. I drove up to Mayhew Lake to start, because I wanted to check out the launch. I was able to get my boat down the launch, but it was a real tight fit. Nice little lake. We saw a mommy moose with 2 babies laying right on the shoreline. I got sick of trolling, so I decided to cast cranks along the drop offs of the one small stretch of shoreline that was out of the wind (relatively speaking). Hooked into a big fish! Got excited because I thought I finally had a lake trout! It was a northern!  never thought I'd be disappointed in catching a 5.5 pound pike, but that's what I was. Didn't bother going to Bearskin, as I knew the wind was too bad again. Went to Poplar, which is a lake I do not like! As is typical, the fishing was no good! He weather was bi polar! It would be bright and sunny, then rain for 20 minutes. Did that the whole rest of the day! Only caught 1 little pike and  1 little bass. Got excited for a minute, as whitefish started surfacing around my boat in the evening. I was hoping I could catch 1 or 2, but nope!    Saturday we were supposed to fish Two Island for a few hours before going home. But it was pouring rain. We didn't even bother driving around to different boat launches. So the trip ended on a sour note, but we still had lots of fun, seen a moose, had our donuts (I highly recommend the bacon maple longjohn by the way), and went to Sven & Ole's. I was going to go camping in Ely in July, but I think we'll come back to Grand Marais instead, and try to make up for what we missed out on due to the weather. IMG_6122.MOV

      I have not been on Rainy much as of late. On June 12, I got 75 walleyes in about 6-8 FOW. On. June 15 (Sanctuary opener) I hit Stangi for several hours and only got four fish. June 17, got 20 fish in about five hours - mostly walleyes on a weed edge in about 8 feet of water. Many on jig with Lunker CIty trailers. Also some good ones on a feather jig. Bass were few and far between. Plus some pike but nothing huge. Biggest walleyes 24-25". Bass 18", pike 29". View my fishing report to see videos of lures that were working.   I did mark lots of fish in deeper water but they were dink walleyes so I did not fish them for long.The dinks are actually harder to catch on lures than bigger ones. They respond better to live bait which I don't use.

      We had a good bite on 1/2 crawlers today! Boated 45 walleyes and kept our limits of fish that were all between 15-1/2" and 19-3/4 "! Released at least 6 slot fish. Largest was a fat 25-1/2 inch fish. Best over all sized fish limit all summer! The walleyes were stuffed with either May fly nymphs or molted crayfish.

      I've fished the hex hatch many times. In wisconsin.The hexs are out at my lakevplace in grand rapids Mn.  its usually a little later on the river. So this weekend into next week and the following week ought to be good. Late in the evening.. like  9:30 on...  I haven't been to the straight for years... I wish you'd let me know how it goes...

      6/24/17     Got out on Washington this morning to target walleyes. Cold and windy! Busy today--a bass tournament going on. We fished several spots with leeches under a slip float for eyes. Only caught one small one, and missed a couple bites that might have been walleyes. Did catch several medium to large smallies and one largemouth. Got off the lake about 10:00 as we saw the first wave of rain approaching. Not interested in fishing cold, wind-driven rain. Guess mother nature doesn't always look at the calendar, which said summer started this week. Good luck, and I will see you out there somewhere.
