Anyone know what the clearest lake in MN is?

Recommended Posts

I was wondering if anyone knows what the clearest lake in Minnesota is for scuba diving purposes. It would be great to go in Minnesota and see some of our favorite species in their natural habitat and see some of their behaviors as well.

Water clarity in feet?

Name of lake?

Location?

Square lake in Washington county has organized diving events each summer. It has amazing clarity.

The clearest I have seen while reading the DNR Lake Finder reports is Ottertrack (21.5' on the Secchi disk), Little Knife(24'), and Knife (21') in Lake Co. It would be a little work to get scuba gear in there though. I would say north part of Superior such as around Isle Royale may be even clearer.

Trout (in St Louis County) has secchi of 16' and I have heard there is some cool stuff on the bottom.

I don't know if it's the clearest in the state, but Square Lake in Washington County is very popular for scuba divers. It's the best in the twin cities at 16 ft water clarity.

Lake Wazee (spl) in wisconsin is more clear, and very popular as well. My son scuba dives and recommends wazee as well.

I was on Woman for opener back a few years ago and that lake was crazy clear. It seemed like we could still see bottom in 20ft of water. I'm sure you could find a few lakes up in that area that have great water clarity

I truly can't say enough of the info you can get from this site and the members on it. Thanks to all that may respond.

I would be surprised if it wasn't Superior. I know it has secchi disk readings of 25-30 feet on average, but I think it can go to something like 50 feet in some areas.

Gilbert, Clearwater near Brainard mn. I was at Fish Lake near Elysian last winter when the dive team from Owatonna was on the lake, I talked to one of the members and he told me they could see about 18 feet when under the ice.

Bad Medicine in Becker County is another awesome, deep, clear lake. Also Pickerel is the same. I know our local dive/rescue team practices there all the time.......

Ottertail County has many lakes with clarity over 21 feet.

A little Trivial Pursuit tip: Eagle Lake just south of West Battle Lake is the only lake in MN that has fresh water coral. Although I know for a fact this isn't true. Snagged some in Silver Lake (across HWY 78 from Battle Lake). wink

Was on Mille Lacs a few winters ago and my dad dropped his glasses down the hole and you could see the shine of the frames in 25 ft of water. Couldn't tell what they were but you could tell that there was something down on the bottom.

LEP is correct and OT Co has a lot of very clear lakes. If Gissert checks this thread maybe he can give us the latest reading on South Turtle. Last year he ran out of rope while doing one of his checks.

I would second Eagle in Ottertail County. This is the clearest lake I have been on (like tap water). Watab also a very clear lake.

Ox lake north of Crosslake...DNR reading of 28+ ft...but it's a private lake, so it doesn't count , I guess.

After diving in Square Lake last summer, I'm not a big fan of that lake. I don't know if it was partially due to the time of year, recent boat traffic or an algae bloom, but we had no more than 5-6' of visibility pretty much everywhere. It does have some neat sunken features though to check out if thats your type of thing. I think there are probably others though that are better later in the summer.

The mine pits in Crosby are really clear, and Minnesota school of diving out of brained does a lot of fun dives up there (great way to meet some other divers, and get a tour of the pits). it is the only place that i have dove where you get to swim through trees in 50 feet of water, and on one side of you is a cliff that drops to 200 and some feet.

    • It might be better to buy a small second unit and link them.    My guess is what you want is not something enough people want to justify implementing.   Personally I have a hard enough time watching a bobber.
    • Welcome to the Forum.  What brand gun is it? Would help to pick choke tubes out.  Size 6 shot should do the trick, but I'm sure more folks will chime in here. 
    • I upgraded my electronics this year to a Humminbird Helix 10. I love it so far with the exception of not being able to split the screen into 4 separate screens. The max that you can do is 3. I would really like to be able to have the map, sonar, down imaging, and side imaging on the screen at the same time while trolling. I emailed tech support and they said it's not something that is an option at this time. Right now when I'm fishing I switch back and forth between map, sonar, and DI and sonar, DI, and SI. Is there anyone else that thinks this should be an option? I don't know see why you can't customize the screen to show whichever features you prefer instead of only using the preloaded options that Humminbird decided on. I have thought about emailing the company weekly asking if they have that ability yet but wanted to see if anyone else thinks it should be an option. 
    • I just purchased a used 20 gauge for my 14 year old daughter. I hunt mostly state land for pheasants. It is a 2 3/4 auto with interchangeable chokes. What size steel shot and choke tube would you recomend for her?
    • I just got back from a work trip to MI. I could not believe the difference in ground cover. We traveled all the way from Dearborn back to Bemidji heading through the U.P.  Most of MI had very little ground cover but WI was flush, green everywhere! I only got to check a few spots at rest areas but I never saw a thing. The ground was dry at most spots on the way home. I'm gonna go hit my spot tomorrow, hopefully it hasn't been picked yet!
    • love those when ya see them!!!
    • Took the kayak crappie fishing opening weekend and when calm always bring with the DSLR with. These turtles are glad the weather has finally consistently warmed up. I always find it funny seeing turtles stacked on top of each other and found a few along with multiple species which was nice.     
    • I was going to hunt wi this weekend but fishing musky with my fly rod is what I will do instead.  Good luck!!!!!!!
    • Anyone still at it?   not sure that i will get Isaac out anymore, will still ask these last few days.   Good luck everyone.
