FIRST LAKE VEGETATION TREATMENT SCHEDULED
Lake Restoration, our contractor for treatment on Lake Johanna, is scheduled to survey the lake and water temperature the week of June 2.  Weather, water temperature, and wind conditions permitting, the first treatment will occur early in the week of June 9.  A second treatment is tentatively scheduled for the week of July 7.  Notice will be sent out to members prior to the treatments, and waterfront signs will be posted after.  Members do not have to mark their lakeshore.  The contractor uses aerial photos and maps to identify properties, and the location of docks, lifts, beaches, and swimming rafts will determine the treatment areas. 

These dates are earlier than last year, and represent the Board's effort to work more closely with the vendor on optimum treatment times.  Curley-leaf pondweed, our only invasive species, is the first plant to appear in the spring.  However, if the water temperature isn't warm enough (greater than 50 degrees), and native species (e.g., Coontail or Northern milfoil) and filamentous algae aren't sufficiently mature, we miss the "sweet spot" for the broadest control.  It's a delicate balance that also has to accommodate the contractor's schedule for other lake associations.  If you'd like more information about treatments, visit our website at www.ljis.org.

STYROFOAM BEADS POLLUTE SHORELINE
Thousands and thousands of tiny, floating, stytrofoam beads have fouled the northeast shore of Lake Johanna in recent weeks.  This shore often receives floating vegetation and trashl carried across the lake by the wind.  At times, the amount of styrofoam resembled snow cover on the shore.  It's uncertain what impact the beads will have on fish or wildlife, but clean-up was very difficult for the affected property-owners due to the amount and size of the beads, the remainder of which are likely to remain in the lake for a very long time.

The styrofoam may have originated from construction or ice-house insulation, or from floats used for docks, lifts, or rafts.  If you have any styrofoam materials on your shoreline, please remove or dispose of them, and do not use styrofoam coolers, insulation, or floats in, or near, the lake.

GOOSE REMOVAL LIKELY THIS YEAR
Our successful goose removal program has kept the resident population of geese in check, well below the large numbers historically seen.  However, with last year's suspension of removal, coupled with the large number of geese using the new run-off retention pond last fall at Presbyterian Homes Johanna Shores, removal may again be necessary this year.  Jennie Michaels will continue to manage any removal activities and will work with the sole contractor that offers the service if warranted by the number of resident geese on the lake.
  
THUMBS UP FOR SHORELINE STABILIZATION EFFORTS
Thanks to the University of Northwestern and the Island Beach Club for their efforts to reduce lake erosion.  Their work is most evident along the University's lakeshore and the Club's boat access channel.  The measures are intended to reestablish native shoreline vegetation that retards erosion, enhances wildlife habitat, discourages lawn access by geese, and prevents lawn run-off from directly entering the lake.

Lakeshore homeowners interested in similar projects can partner with the Ramsey Conservation District and the Rice Creek Watershed District.  The two organizations will help finance the costs of a project.  To find out more about their program, contact Joe Lochner with the Ramsey Conservation District at 651-266-7273 orjoe.lochner@co.ramsey.mn.us.
  
WINTER ICE OUT
Winter ice went out on April 21 this year. This was about a week earlier than last year's date of April 29, the latest for the lake since dates were first recorded in 1983.  Visit the LJIS website to see the complete history and other Lake Johanna resources.
