About Us

Lake residents formed the Mooney Lake Association (MLA) in 1991 out of concern for decreasing water quality and heavy algae growth in the lake. In 2008, under the guidance of consultants, the MLA developed a lake management plan to identify strategies to improve the lake’s environment. In 2010, the MLA received non-profit status, allowing the association to apply for grants to support restoration projects.

It’s our mission and overall objective to protect the beauty, recreation, and overall ecosystem of Mooney Lake.
