Access could remain closed for as long as 3 weeks. |

| Wow, take three weeks of the constant pressure off of those fish. They will be all set up and ready to eat when that launch opens!

| looks like it may be closed beyond the initial 3 weeks they first stated as the sign now reads until further notice.. saw what looked like a 50 porpoising just beyond the yellow floaties. they need the rest from being pounded all summer.

The District intends to extend the closure of the Lake Independence boat access in Baker Park Reserve into early November to conduct a more aggressive treatment for zebra mussels in that area. Three chemical treatments have been conducted within the barrier surrounding the access area since October 6. Results have been mixed, due primarily to restrictions on the dose of chemical that can be applied under the current product label.
The Minnesota DNR expects to obtain a variance to this restriction that will allow us to treat more frequently and at higher doses inside the curtained off area, subject to certain monitoring requirements. Those applications could start as early as Thursday October 30, and we would need to keep the barrier in place for up to a week after the start of the treatment sequence to achieve maximum effectiveness. Ideally, the boat access would be re-opened no later than the week of November 10. We ask for your patience as we test this new zebra mussel control strategy on Lake Independence. |

| Does this treatment have any negative effect on the food chain? Forage, other game fish etc.
Thanks! |

No, those yellow "floaties" you see in the picture are actually a curtain that extends to the lake bottom, which keeps the chemical contained within that area. I don't remember if they are using zequanox or copper sulfate. The copper sulfate will kill everything within the curtain, but the zequanox shouldn't. But, this is a small area of the lake and it should have no impact on lake's fishery. |

| Copper kills invertebrates. Not fish. At least at the levels that are using and or wanting to use. |

Copper sulfate most certainly can kill fish. |

Location: new richmond, wi. & isle, mn | What makes them think the veligers(larvae) aren't all over the lake? |

| ^I'm fully aware of that as I've kept marine aquariums for 20 years and have used copper treatments. This is a tiny area compared to the lakes size and therefore not enough to kill fish. Inverts are far more sensitive to copper than fish and lower doses that will kill inverts don't kill fish. I suspect the wall is more for keeping the copper in to kill the invasives making it more effective than it is to keep fish out of harms way and to reduce diluting of the copper. |

They very well could be. From what I understand this was thought to be an infestation in its infancy, so this treatment is partially experimental to understand effectiveness of the chemical used and what concentrations are necessary. And if the infestation is limited to this area, perhaps a rapid response treatment can be effective at staving off an infestation before it takes over the lake.
I believe, but am not certain, that this is being paid for by the Independence Lake Association. I can check on more details about this treatment. |

I think we're saying the same thing. The concentrations within the curtain are definitely high enough to kill fish that are within the curtain, but the rest if the lake is not a concern.
Zequanox is a dead bacteria strain that when ingested by zebra mussels it destroys their digestive system and kills the zebra mussel. It is an effective product, but it isn't likely to be used to treat an open water system.
