The Aquatic Plant Management (APM) Committee is responsible for managing the aquatic plant growth, both Invasive and Indigenous, throughout the waterway. We will clearly communicate to the WWMD Board and Owners through monthly board meetings, regular reports and updates to this Website. Click here to see the latest meeting minutes, which include committee reports.

Aquatic plant conditions change on a continuous basis. Effects of the seasons, floods, droughts, heat waves and dam levels affect the Aquatic Plant population in different ways. It is the role of this Committee to explore, recommend and implement the use of all appropriate approaches possible to manage these changing conditions in a cost effective manner.

Navigational Treatment – July 21st

Our treatment provider, Wisconsin Lake and Ponds Resources, was out on the water again on July 21st. The map showing the areas treated is below.

Navigational Treatment – June 21st and June 26th

Our treatment provider, Wisconsin Lake and Ponds Resources, was out on the water again June 21st and 26th to treat for Navigational Access. Normally they cover the whole waterway in one day, but due to the unusually high growth this season they had to return to complete the treatment. The maps showing the areas treated are below.

Navigational Treatment – May 22nd

The first navigational treatment of the season was completed was completed on May 22nd. We treated approximately 12.5 acres. Interactive map shown below.

Aquatic Invasive Species Treatment Completed

The 2017 treatment for Aquatic Invasive Species (AIS) was completed the first week in May. Areas to be treated are identified by surveying the waterway to identify where AIS is present. These maps are reviewed by the WDNR and we treat all areas that we get approval for and our budget allows. Some areas were not treated as local residents wished to ‘opt out’. The map of the treated areas can be seen here.

Proposed 2017-2018 Over Winter Drawdown

At the WWMD Monthly meeting on 4/27/17 the Board decided to stop the implementation of the over-winter draw down for the 2017-18 season. In a close vote (4-3), concerns over the impact on the EcoSystem Restoration project and resolutions from the Town, Village and SEWFRC outweighed the potential benefits and cost savings of this technique.

Flowering Rush Found in Our Waterway

During the herbicidal treatment done on June 2nd (2016) we identified a new Invasive Species in our waterway. The WDNR was with our treatment provider and confirmed that we have a small amount of Flowering Rush growing in some areas of the shore line. When caught early, this is easy to remove with hand pulling. Wisconsin Lake and Ponds Resource (WL&PR) is recommending a full survey with hand pulling being done at the same time. This work is covered by a WDNR Rapid Response grant. Attached here is the grant application.

Starry Stonewort

A new invasive species, Starry Stonewort, has been detected in some local lakes. This species has been known to cause nuisance conditions in Michigan, New York and Indiana but is new to Wisconsin. Our waterway has been surveyed and none has been detected. Our Clean Boats/Clean Water program is checking boats at the Library Launch and we have no reports of any being found.

The information we have received from the WI DNR clarifies that Starry Stonewort does not kill fish and the lake will not ‘die’ if this plant becomes established. However, it can affect the aquatic plant community and alter the aquatic habitat in the waterway. We will include Starry Stonewort in our pre- and post-season surveys and if it were to be found it will be included in our Lake Management plans.

The committee will continue to explore new approaches and adjust how we implement the current techniques. We are always open to input and feedback, if you have heard of other tactics, please feel free to let us know.
