For a sample of an ice shove on Lake Metonga, please click on the “Ice Out Video” link below.

Ice Out Video

An ice shove, ice surge, ice heave or shoreline ice pileup is a surge of ice from an ocean or large lake onto the shore. Ice shoves are caused by ocean currents, strong winds or temperature differences pushing ice onto the shore, creating piles up to 12 meters (40 feet) high. Some have described them as ‘ice tsunamis’, but the phenomenon works like an iceberg. Witnesses have described the shove’s sound as being like that of a train or thunder. Ice shoves can damage buildings and plants that are near to the body of water. Arctic communities can be affected by ice shoves.

Eurasian Water Milfoil (EWM):  As predicted, our problem has grown to over 250 acres.  The DNR has agreed to allow the LMA to treat 60 acres of EWM this year.  The DNR grant funded portion is $33,893.00 and the LMA funded portion is $28,559.80.

Clean Boats – Clean Waters:  The LMA will sponsor the program again this year.  A grant was received from the DNR for $7,912.8 to hire inspectors.  The State will fund $75% ($5,934.60) of the total budgeted cost.  The Mole Lake Tribe provided $4,000.00 to support the program.  Gary Mignon has agreed to be responsible for running the program.

2015

Eurasian Water Milfoil (EWM) beds (23.9 acres) were treated with a combination of 2-4-D & Aquathol Liquid Herbicide on 5/28/15.  These beds were prioritized because of their proximity to the city beach and launch area.  The cost to the Association was $23,790.20.  A survey of the EWM beds will give the Association direction to the herbicide selection for 2016.

Clean Boats – Clean Waters ran from May 23, 2015, through September 9, 2015.  A total of 776 hours were performed by the inspectors.  Boats entering the lake came from as far away as Michigan.

Reference:  Fall 2015 Newsletter

Recorded 30 inches of ice on the lake. 2014 Fall survey identified Eurasian Water Milfoil (EWM) growth and proposed control strategy was to perform Herbicide treatment 77.6 acres.  A grant was filed with the DNR on Feb 1, 2015. The DNR would not provide any herbicide treatment funds in 2015, but would apply the funding for 2016. Considering critical EWM growth areas, the Association Board decided 21.6 acres should be treated and would be at the Association’s expense.  Cost to do this treatment would be $21,860.08.  Additional cost for pre & post treatment surveys plus submitting results including effectiveness of the treatment to the DNR of $7,746.50 for a total of $29,200.08.

Bullhead Harvest:  900 were harvested.  An aggressive harvest in previous years has significantly reduced an abundant bullhead population.  As a result, the Perch population has increased considerably over the years.

Tribal Harvest:  As soon as the Ice Out occurred, the Mole Lake Tribe speared a total of 681, nearly 400 less that what was speared in 2014.

Clean Boats – Clean Waters:  A grant was received from the WDNR to financially support hiring three inspectors to cover the boat launches at the North and South ends of the lake.  The state will fund 75% of the total budgeted cost.  Schedule will begin on May 23rd and continue through September 8th.  An inspector training session was conducted by the WDNR staff at the Crandon Public Library.

2014

EWM Treatement:  Since the Association did not receive DNR funding, the Board of Directors approved herbicide treatment of on 14.9 acre EWM bed on the southeast end of the lake, plus hand-pulling a 2.2 acre bed on the north end in front of the City Beach and a 2.8 acre bed at the south end in front of the boat launch.  Aquatic Plant Management, LLC was contracted to provide this service which was accomplished in July at a cost of $4,986.00.

Bullhead Harvest:  Total pounds harvested 3,836 which equates to 5,856 fish.

Clean Boats – Clean Waters:  ran from May 23, 2014, through September 9, 2014.  A grant from the DNR & the Chippewa Tribe were used to pay the salaries of the three inspectors.  A portion of the funds were used to purchase and erect a CB-CW sign at the south boat launch.

Total snowfall recorded 110.3 inches. Recorded 30 to 36 inches of ice on the lake, covered with 2 feet of snow. DNR Grant request was denied due to lack of funds to cover all proposed projects in the state. The board approved proceeding with an alternative plan to hand-harvest-pulling at the City Beach and in front of the County Park launch.  Treatment EWM sites were contracted to be done in May or early June.  Total cost for this plan was $23,667.13.

Clean Boats – Clean Waters:  Inspector training session was conducted by WDNR staff on April 30, 2014, at the Crandon Public Library.  A grant was received from the WDNR to financially support hiring three inspectors to cover the boat launches at the North and South end of the lake.  The state will fund 75% of the total budgeted cost.  Schedule will begin on May 23rd and continue through September 8th. A new sign was installed at the South end boat launch to lake users to clean their boats and equipment to prevent the spread of invasive species.

Bullhead Harvest:  28 hours of harvesting bullheads was performed.  The sizes captured were from 7 ½” range to 10 to 11 inch range.  Total pounds harvested were 3, which equates to 5,856 fish.

2013 Treatment Sites & Map

Clean Boats – Clean Waters:  The cost of this project was completely funded by a grant that was received from the DNR & funding from the Chippewa Community to support hiring three inspectors to cover the boat launches at the North and South end of the lake.  Inspections started May 25th through September 14, 2013.

Eurasian Water Milfoil (EWM) on June 3, 2013, a pre-treatment survey was conducted.  This pre-treatment survey verifies if there is any change in the beds that were mapped last fall.  This survey covered 59.8 acres to 60.0 acres.  Herbicide treatment was applied on June 6, 2013.

Snowfall total was 83.6 inches.

Eurasian Water Milfoil (EWM):  A survey in the fall of 2012 was reviewed only to determine that the effectiveness of the May 30, 2012, treatment of 58.3 acres was not as effective as hoped.  The conclusion was that the treatment is effected by the wind & water movement.  Nine beds were marked to be treated with the balance of the grant funds and the Association would fund the rest.

Clean Boats – Clean Waters:  Inspectors will start on May 25th through September 8, 2013.  The Association received a DNR grant and a donation from the Chippewa Mole Lake Tribe to fund this project.  An inspector training session was held at the Crandon Public Library on May 24, 2013.
