Dear Green Lake Residents,

We would like to share an important update regarding the efforts to manage milfoil on Little Green Lake.

For over 16 months, the Green Lake Association (GLA) has worked closely with Lake Management, EOR, and the DNR to implement a whole-lake Fluridone treatment to address milfoil. We know many residents have been anticipating this treatment and the benefits it would bring to the health and enjoyment of our lake.

Unfortunately, on June 17, the DNR denied approval for this whole-lake treatment. The denial was based on:

- Insufficient Early Season Milfoil (EMW) density during surveys,
- Concerns about potential fish kill due to low oxygen levels in the lake, and

- The DNR’s determination that targeted spot treatments could be just as effective while reducing risk.

We understand this news is disappointing after such long and careful preparation. However, we have already pivoted to a new plan in coordination with our Lake Management consultant and the DNR.

Just last week, the DNR approved a new chemical treatment: Triclopyr 3SL, which will be used on both Little and Big Green this year. This treatment is designed to inhibit milfoil growth for 1.5–2 years while protecting water quality and fish populations. Another advantage of using Triclopyr 3SL is that for the past six years, we have used 2,4-D/Weedar 64 for treatment, and plants can develop tolerance to a chemical over time. Switching to Triclopyr 3SL is a proactive decision to increase treatment effectiveness while diversifying our management approach.

Currently, no treatment date has been scheduled. We will begin detailed planning in the following weeks, including:

- Ordering the approved Triclopyr 3SL chemical,
- Preparing logistics and drum locations,
- Aligning treatment with the best weather conditions for optimal results, and
- Organizing a volunteer team to assist with the treatment day.

We appreciate your patience and understanding as we adapt to these changes to continue protecting Green Lake effectively and responsibly.

If you have questions or would like to help with this very large treatment, please reach out.

Thank you for your continued support.
