Our Lakes.

Druce Lake and Third Lake are within the boundaries of Mariner's Cove and the Village of Third Lake and are accessible only to residents.

Druce Lake

Druce Lake has a sandy beach located on Mainsail Dr south of Galleon Ct. The beach is for residents only, so you have exclusive access for swimming, fishing, boating and more!

There's a boat launch near the Druce Lake Beach for non-motorized boats. Many residents enjoy stand Up paddle boarding and kayaking on the calm waters of Druce Lake.

Third Lake

The bigger of the two lakes, Third Lake allows motorized boat traffic. There's a neighborhood boat launch located off Mainsail Dr. There's always a lot of activity on Third Lake in the summer months!

Third Lake Pier
Please be aware the pier at the Third Lake launch is usually removed in the fall on or around November 1st - but this can vary by two weeks earlier or later. Please plan accordingly.
