Spraying Weeds = dead fish

10 posts in this topic

Once again this year many lakes have already been sprayed for weeds.   Why spray right during the spawn?  Here is what I found today fishing a tournament up on Goose Lake in Chisago County ..... dead 8-9" sunnies all over the place.   Do the DNR/Homeowners Associations/anyone else that sprays weeds understand that it kills fish - so frustrating to see this year after year.

Decaying weeds suck oxygen out of the water and add to the increase in algae bloom as well. 

It's very sad to see. There are lakes in the area that had fantastic fishing for larger than average fish. In the metro area to boot. But once they started killing off the weeds every year taking away the defined weed lines and removing cover....

mediocre and average fishing at best.

As far as I know the culry pondweed dies off late spring early summer so whats the point of killing it.  Drives me bonkers

Yep, my home lake got sprayed and EVERYTHING is dead.  Water is very clear until they spray and now it's getting green.  I like how lakeshore owners b**ch about us fishing their docks, but it's perfectly okay for them to spray the weeds and make the lake borderline unfishable.

I wonder if an alliance could be formed with a group that does advocacy work around water quality - The Nature Conservancy or some such. The only way this will change is if the DNR is forced to change practices around spraying.

Bone, I was up there with you on Saturday.  Pretty sad to see dead fish all over the lake and not just a few here and there, entire weed flats littered with them.  I struck up a conversation with the DNR invasive guy about a week ago at White Bear Lake and told him about the dead fish and the decline in fishing at many of these lakes since they started spraying these lakes over the years.  He admitted that one of the sprays they use is pretty much the same as Weed-B-Gone, the same stuff you use in your yard.  He said if we the fisherman get enough people together and go to the legislature and the appropriate people within the DNR, we actually could make significant headway on reducing the spraying.  He said it will take time, because as we all know, this is very political.  From talking to him, it sounds like the lake associations and lake shore property owners don't have any opposition and are doing whatever they want.  He did say we have a lot of power as fishermen due to the economic impact we have and the DNR will listen to us...who knows if he was blowing smoke up my rear, but I'd bet it would be worth a shot.

The fish die off may not have anything to do with spraying there is a virus that kills mainly panfish when the water warms. thousands were on Lake Independence a week ago. Also that curly leaf pond weed looks healthy.

It's actually a bacteria called columnaris but yes, it does kill fish (particularly centarchids) every spring, usually in May but I still saw fish affected last Saturday (white mouths is the main symptom you will see in fish on the brink of death).

    • Sounds perfect, thinking your guys reviews will seal the deal for me once I can see one in person again, a hyfax kit will also be on my list as I plan on pulling it behind my sportsman 570. Thanks for the review also AAmerican, it's early to be thinking ice fishing but I'm sure there's people out there like us that are a little anxious!
    • The Chippewa flowage would be a great place to start. I will be honest. Walleye are not what I have ever chosen to Target when I fish up there but the flowage is a great fishery.    Nelson lake would be another choice.
    • I have had 3 of the otter pro xt's, a cabin, lodge and resort. I still have the resort and recently purchased the cabin. I have not had many different brand portables but have fished in other brands buddies have. They are the nicest portables I have personally owned and until I try something I like more I wouldn't change from them at all. The resort is heavy and not something I like dragging far by hand especially loaded with gear and much snow on the lakes. But it has tons of room and I have fished 4 people in it before, a little tight but doable. The cabin I purchased for more hand pulling and an extra for if I have people along. They are very warm and I have fished in them down to -30 deg F. A regular buddy heater keeps them plenty warm, if it isn't to cold or the house is banked well its easily t-shirt weather inside. The resort needs a big buddy heater for colder days sometimes due to the larger size but isn't terrible with a regular. Overall very happy with them all and have been very durable. Also no dripping of water from the ceiling. Highly recommend a set of hyfax for the bottom. I had over 1000 miles pulling my old lodge and they hyfax held up great but I always pulled on snow and not across asphalt much at all.   Changes I have made to them: - added a battery box and inside LEDs  - used stainless screws on the band that hods the fabric to the tub only because I don't like the look of the rusted screws.     If you think you'll be purchasing one I would recommend stopping at a Gander Mountain if you have one near by and getting a set of hyfax since they are going out of business there is a good amount of ice gear. I found hyfax recently there for $15 a set.
    • We are on Lake Edward at WildWoods RV resort just north of Merrifield, MN. It is nice just driving up, unlocking it, playing for the weekend and locker her back up and leaving the frig on.  They let Atheists and Jesus freaks all in!
    •   My wife and I are starting to think about parking ours someplace. I'm tired of trying to get reservations and having to hook and unhook and all that goes with a weekend of camping. Plus I would like to have the toys available like 4-wheeler and boat.   We are looking at places up north. We know several people and like the Emily-Outing-Remer-Hill City area. I think you a further west, right? Brainerd area maybe?  
    •   5 years at one campground until they went private and wanted 60-70g's per lot with one-just-like-silly-me-o-en fees which were about what we were paying yearly already on top of that!  12 years where we are now with way bigger lots.
    •   Too bad the previous owner didn't know what they were doing. Never, ever use silicone on a rubber camper roof. I learned that the hard way many years ago.....   At least you have a good reason to have to go to the camper this weekend    How long have you been doing the seasonal thing?
    • Thanks for the reply, sounds about like what I expected and I really like the square tubing on the otters compared to clams round cheaper setup. Anyone seen any changes to the new otter lineup for this year? 
    • Last weekend spent some time re-sealing a small seam leak on a trim edge. Found out the owner before us had a leak on the same trim edge spot and left out a screw!! Also washed down the canopy and the ever reoccurring black streaks around the roof edge.   This weekend may go back and clean out and reseal a few other areas the passed own made a mess of sealing with sillycone! Using Butyl rubber this time as silicone can be pulled right off after a few years.
