Zebra mussel update - your help needed

posted Sep 27, 2018, 12:34 PM by Keith Gilbert
We notified you on 8/23 that Zebra Mussels, an Aquatic Invasive Species, were discovered at the public access in Lake Johanna. Since that time, we have been working with the MN DNR, Ramsey County, and Blue Water Science to survey and scope the extent of the problem and best understand our options for a response.
The LJIS contributed $400 to help fund an extensive survey of 13 sites around the lake searching for additional mussels. The searchers found two more mussels: one at the public access and one along the shore SE of the access. You can read the full survey report here.
Because of a variety of factors described in the report, “A zebra mussel eradication effort would have a low probability of success and is not recommended. Long-term management should include water quality monitoring and potential small scale control efforts in the future.”
So at this point, we need to monitor the situation and wait. This is where you come in. We need to gather as much data as we can about the presence (or lack thereof) of zebra mussels. This is what we are asking you to do:
1. When you pull your dock, boat, boat lift, irrigation system intake hose, or any other equipment you have in the water along your shoreline, inspect it carefully for zebra mussels. They can be quite small, so look carefully.
2. If you see anything that you suspect to be a zebra mussel, take a photo and notify one of the LJIS board members right away.
3. Go to this link, locate your address, and report via yes/no whether or not you located any zebra mussels. It is really important that everyone reports in, even if you find nothing.
Thank you in advance for your help!

P.S. A ray of good news in all of this is that Blue Water Science found “very little” Eurasion Watermilfoil during the inspection for Zebra Mussels.
