Lake Minnetonka Water Clarity

6 posts in this topic

I live real close to Lake Minnetonka, and this has been my first serious season of ice fishing. One of the things that has suprised me is how clear the water is. One of my biggest gripes with those who use the lake during the summer is the siltation they create from the waves of their boats/jet skis. In the middle of the summer the water clarity on LM is about 12", you can stand in knee deep water and not see your feet. Right now, with the ice on the lake, I can look down my hole and see my jig in about 14 FOW. It's fun to site fish for sunnies & crappies like that. But I won't swim in the lake during the summer because the water is so gross. I am aware of a small lake/large pond in Wright County where 3 land owners own the entire lake shore, and they only use electric trolling motors or paddle. The lake is super clear, even in the summer. You can see all the lake weeds growing on the bottom. I wonder how much better the fishing on 'Tonka would be if the water was not so churned up from speed boats? The water would be colder and hold more oxygen, both of which would be good for the fish populations.

There are a million different reasons why some lakes are more clear than others. Speedboats are a huge annoyance, but I don't think churning up the water makes a whole lot of a difference on the clarity. The main problem is runoff bringing excess nitrogen and phosphorus into the lake, which contributes to algae growth. Stuff like the McMansion owners spraying fertilizer on their lawns and a rainfall bringing it into the lake. With storm drains emptying into a lake, nutrients from miles away will drain into the lake. In the winter there is less sunlight and the sunlight there is has to pass through 2 feet of ice. Needless to say, photosynthesis is knocked way down, the algae die, and the lake gets clearer. When the spring/summer comes, sunlight increases and the all of the ingredients for a massive algae bloom are there --- then you can only see down 12"

The lake you mention in Wright county may be clear, but I bet it is less from the lack of gas motors and more from the watershed. Not that gas motors are particular good for a lake.

The farther east you go on Tonka the clearer it is, the farther west you go on Tonka the darker it is. On the west side you cannot even see a muskie bait coming back to you, on the east side you can see several feet into the water on a clear, calm day ..... even in the middle of summer.

Is that because of the amount of runoff?

I think it was something to do with the watershed to Tonka. There used to be sewers going into Tonka back in the day from miles around. Which was a lot of farmland and I don't think we knew about the effects of fertilizer back then. I thought the sewers have been rerouted back in the 70's or something. I guess I should've paid more attention. There was a show on PBS about Tonka last year. Interesting

I also heard that house boats dumped the crapper in Tanger Bay. That bay is really green while Browns bay is pretty clear.

Either way there's huge fish every where in that lake.

      7/19 Day 5   Day 5 was spent celebrating my Isaacs 11th birthday!  Lots of cake and catering to him.  The exciting typical swimmimg and paddling ruled the day.  Grandma and grandpa DeZurik came up to celebrate his birthday as well.  Always nice to get both sets of grandparents together at the same time.   Fishing continued slow even more.  Still a successful night though. The birthday boy conceded his seat in the boat so grandma and grandpa cpuld join me for the evening fish trip.  My folks in all truth haven't been fishing for 2 years or more.  It was just nice to get them in the boat.   I struggled as the acting to put them on a consistent bite.  Mom as able to scratch out the biggest walleye at 17".  Dad brought home the honors of most fish caught landing a 14" and 15" walleye, 8.5" bluegill, and 2 perch as big aa his leech! I mustered up 1 small pumpkinseed.

      I like drifting with them and snap jigging them with a controlled fall...Almost every time you'll feel that tick just as it's hitting bottom... Last time I was on mille lacs that's all I could get them to go on. As far as colors I'd just match the forage Tullies in the lake use blue,purples,silvers....Perch use perch colors.. I think the jiggin rap is my new favorite way to fish, but it gets scary with them little hooks when you got a big eye on lol.

      Fished Big Sandy from 8-2 today and got 10 eyes (no keepers) keeper crappie and perch.... Marked tons of fish, but it was tough to get them to go, Lindy rig with a half crawler was the best by far. I tried leeches,jigging rap, jig n plastic. Points and reefs were the spots, later in the day a lot of fish were off the edges of the reefs... Just one day this year I'd like a happy medium weather wise, either I'm in 4ft rollers or 90 degrees with zero wind haha.

      According to Al Linder you can do it all with them...on his video that I watched a while back he was in deeper water throwing into 15 feet and working it back to the boat.  I have not tried it yet but will have to sometime this year.  Sand or gravel bottom would be the best.

      Just started playing with these this week as a friend has been have goos luck all summer with them on the Cass lake chain. I have not any success yet but not real sure on the best way to use them with my set this week.  My friend searches pods of fish out with electronics then spot locks and vertical jigs. I have no electronics or spot lock so I have been control drifting and jigging.   My questions...   Is there a depth they work better in, shallow vs. deeper?   Better vertically jigged vs trolled vs casted and jigged?   prime colors? of course my be lake dependent.   typically, aggressive jigging vs subtle jigging?   Thanks for tips

      Yes, insured. I will ask the adjuster, thanks.

      Thanks cliff and lb I have actually had better luck with the puppet minnows from northland but I have mainly jigged them vertically definently is a fun way to fish

      I've been trolling at about .5mph while using a jigging rap. This way one guy can still drag a lindy. I keep the front hook intact but my boat has contributed about half a dozen to the lake so far this summer. Im still working on getting the hang of it. If I know I'm in a rough area I will attempt to keep the jig from hitting bottom which still seems to be effective. I did pick up a couple off brands that don't have a front hook that I want to try. This is just what I have been toying around with, I'm definitely not an expert at it.

      Hi Everyone, a couple of questions, I know there is free public boat ramp in Stillwater just above the lift bridge. Is there another public boat ramp further down river? I thought I read somewhere that Beanies is or was becoming a free public boat launch. Is that the case? Also, I am thinking of heading there on Monday to try my luck. Any tactics/depths/areas that have been producing for anyone?
