Information Bulletin #12

posted Aug 1, 2011, 11:40 AM by Keith Gilbert
The second Lake Johanna weed treatment was delayed by high water levels after the recent downpours. Our contractor, Lake Restoration, has now scheduled the second treatment for the end of the week of August 1 or the beginning of the following week. They will treat for all weeds but vallisneria, which is most responsive to treatment early in the summer. They also will treat localized areas with filamentous (stringy) algae growth; however, there is no treatment for the algae that turns the water green.

Lake Restoration used GPS to identify properties during the first application, so they do not need to see your dock stickers for the second application. However, they still would like you to flag the area that you want treated. If they don't see any flags, they will treat based on the location of your dock, beach, swim floats, etc. and the amount of your lakeshore footage approved by the DNR for treatment.

Other news:

Lake levels are very high and floating debris may still show up in the lake. Given the possibility of more heavy rainfall, you might want to remove anything that floats along your lakeshore waterline.

At our request, Ramsey County has placed a new sign at the public access ramp area asking boaters to remove all vegetation from boats and props before launching. Lake Johanna is still free of Eurasian milfoil, and we want to do everything possible to keep it that way.

Goose removal was completed on June 22 during their molting season. If you still have problems with grazing geese on your lawn, you could try leaving a strip of unmowed vegetation as a natural barrier between your lakeshore and your lawn. Once established, the geese are reluctant to cross the barrier because of fear of predators hiding in the vegetation, and the vegetation also reduces runoff to the lake.

Lake Johanna was featured in the Minneapolis StarTribune series on metro lakes on July 15. If you missed it, a link to the article is posted on our website <www.ljis.org>

It's not too late to join us for our annual picnic on Thursday, August 11, at Tony Schmidt Park at 5:30 pm. RSVP to Mari Salveson <mssalveson@hotmail.com> or Diane Bronson <dbronson@comcast.net>
