NOTICE: GREENWOOD LAKE DRAWDOWN TO COMMENCE IN THE FALL OF 2027

The water level management plan for GWL calls for an optional 5' drawdown every four years. While 2026 is a scheduled drawdown year, due to the commencement of a NJDEP capital project to repair/upgrade the Greenwood Lake Dam sluice gate mechanism, the Greenwood Lake Commission has approved rescheduling the next drawdown to commence in the Fall of 2027.

Background on this decision is as follows:

Over time, the operation of the Greenwood Lake Dam sluice gates has become increasingly difficult and more unreliable as a result of normal use and aging of mechanical components.
In 2025, the Greenwood Lake Dam was given priority for a capital repair, the initial phase of which was commenced in June 2026 by the New Jersey DEP.
The capital project will include Project Engineering & Planning, RFP Process & Contract Award, and Project Implementation & Completion.
When available, updates to the capital project schedule will be posted or made available on GWLC.org or via link to NJ DEP website.

This project is an important element of NJDEP's work to maintain the Greenwood Lake Dam infrastructure and is fully supported by the Greenwood Lake Commission. Once completed, future drawdowns can proceed again as optioned every four years.

Dear Elected Officials, Environmental Leaders, and Community Stakeholders :

The Greenwood Lake Commission cordially invites community leaders, environmental stakeholders, municipal officials, and public representatives to attend an important presentation on the findings of a comprehensive one-year scientific study examining the nutrients and environmental conditions contributing to Harmful Algal Blooms (HABs) in Greenwood Lake.

This informative session, presented by Dr. Meiyin Wu of Montclair State University, will provide valuable scientific insight and data critical to future lake management, environmental protection efforts, and regional collaboration. Your attendance and support are greatly appreciated as we work collectively toward preserving the health and sustainability of Greenwood Lake and its surrounding communities.

Stop the Spread, Save the Lake

Stop the Spread. Save the Lake.

Dear Concerned Residents and Friends,

Our lake is under threat from rapidly spreading invasive w**ds that are choking waterways, damaging wildlife habitats, and making recreation difficult for everyone who enjoys this treasured
resource.
The annual herbicide treatment is essential to protect water quality, preserve property values, and ensure the lake remains safe and enjoyable for boating, swimming, fishing, and family recreation. All can contribute to the treatment of the lake, however the application is for NJ waterfront Homeowners only at this time. The Village does a separate treatment.
Unfortunately, funding is not available this year through the Commission or surrounding municipalities. Without treatment, invasive species can quickly take over, causing long-term
ecological damage that is far more costly to reverse.

**This lake belongs to all of us — homeowners, visitors, families, and outdoor enthusiasts. **

We are asking the community to come together and help fund this critical treatment. Every donation makes a difference. Your support will directly fund efforts to:

• Control invasive aquatic w**ds
• Protect wildlife and natural habitat
• Maintain safe recreational access
• Preserve the health and beauty of the lake

Time is critical — treatment must occur soon to be effective.
Please consider contributing and sharing this message with others who value our lake. Together, we
can protect this irreplaceable community resource.
As of now, our plan is to apply one application of herbicides to treat the w**ds, approximately
Early-May. The timing of the application depends on the w**d growth and weather conditions.

SAVE OUR LAKE BEFORE IT’S TOO LATE!!

🚩 For NJ Waterfront Homeowners Only
