Consider this mechanical means to help dissipate Duckweed and Weed Chop at your shoreline. Please contact WLCA via this website with any additional questions. Note: This device will not eliminate the need to physically remove larger/thicker weed masses from your waterfront, but it will help in your efforts.
Permit Exempt Aquatic Weed Control by Property Owners/Tenants - The 625 sq. ft. Rule Explained
The Indiana Department of Natural Resources has recently created an infographic brochure to explain the extent of treatment and rules under which an owner or tenant of land adjacent to public waters can, themselves, control aquatic vegetation along their own shoreline frontage. It is important to note that ALL conditions indicated in the brochure must be met in order to be exempt from the permitting process otherwise required by the IDNR. Failure to meet ALL itemized conditions will put the owner/tenant at risk of prosecution.
Webster Lake residents should consider that the WLCA annually secures a permit for third-party herbicide treatment of more than 60 acres of channels and shorelines on Webster Lake. Therefore, owners and tenants may wish to delay any consideration of additional shoreline vegetation self-treatment until approximately 2 weeks after the WLCA's shoreline and channel treatments have been applied. Treatment results are generally visible within 2 weeks. Advance notice of WLCA-sponsored shoreline and channel treatments is made available to owners/tenants who have provided their e-mail addresses to WLCA via the Contact Us page on this website. Informational bulletins are sent via a secure group e-mail service (Mailchimp). Yellow warning notices are posted on property shorelines by the herbicide contractor on the day of treatment.

January 2024: Updated 2023 Annual Vegetation Management Plan including recommendations for 2024 treatments. This report was prepared for the WLCA by Solitude Lake Services as required by the IDNR for the WLCA to participate in the Lakes and River Enhancement (LARE) Grant Program. Updates and treatments for 2024 will be completed by Aquatic Weed Control, Inc, Syracuse, IN. The LARE Grant will cover 80% of the costs for preparation and review of a required Annual Vegetation Management Plan and 80% of the cost to treat up to 100 acres of Eurasian Water Milfoil (EWM) and 50 acres of Curly Leaf Pondweed (CLP), invasive weed species. WLCA is responsible for the remaining 20% of these treatment costs and 100% of the cost to treat an additional12 acres of EWM that was added to the permit but not to the LARE Grant. Also, WLCA pays 100% of the cost to treat approximately 69 acres of native and invasive species impeding navigation at shorelines (56.6 acres) and in channels (12 acres). WLCA member dues payments and extra contributions to the Weed Fund are used to cover the cost of these herbicide treatments. Herbicide treatments of weeds in the greater lake and at shorelines and channels are essential to the improvement of lake navigation and in minimizing weed chop which is caused by boats driving through weed beds.

September 11, 2017: Here is a slide-show presentation prepared by Aquatic Control for the WLCA September 11 Board of Directors meeting. Please note the color-coded map of Webster Lake prepared from data collected in 2015. This data influenced the decisions made in 2016 relative to weed treatment permits and LARE grants. Data collected in 2017 has been submitted to the IDNR for their consideration regarding treatment of Webster Lake in 2018.
August 2017: Volunteer WLCA officers and directors spent approximately three days during August 2017 mapping the lake with a Lowrance sonar unit in preparation of an annually required IDNR aquatic vegetation report. See Entry at May 2017 below for a more detailed description.
June 22, 2017: A non-selective weed and algae treatment of the shoreline and channels of Webster Lake was completed by our weed management contractor at a cost of $24,604.
May 10, 2017: A selective treatment was applied to the remaining 60 acres (down from 155 acres the prior year) of the invasive weed Eurasian watermilfoil throughout Webster Lake. 80% of the treatment for watermilfoil was reimbursed by a LARE Grant, leaving WLCA a balance due of $2,884. Also, the shoreline and channels in the Miller's Landing area of Webster Lake received a special treatment for invasive curly-leaf pondweed that was growing in abundance. The curly-leaf treatment was paid in full by the WLCA at $4,800.
May 2017: Volunteer WLCA officers and directors spent approximately three days during May 2017 mapping the lake with a Lowrance sonar unit in preparation of an annually required IDNR aquatic vegetation report. The initial cost of the Lowrance unit was $1,700, including mounting brackets. Annually, WLCA pays a licensing fee of approximately $900 which allows the uploading of the data collected and the creation of a map showing the location, growth, and volume of vegetation in the Lake. Previously, the mapping was done by an outside contractor at an annual cost that exceeded the purchase price of the equipment and licensing fee.
September 13, 2016: Here is a slide-show presentation prepared by Aquatic Control for the LARE Grant Public Hearing held 09-08-2016.
