Senate Bill No. 313, also known as Public Act No. 25-58, mandates the establishment of a speed limit for motorboats and personal watercrafts on Lake Mashapaug in Union. The bill requires the Department of Energy and Environmental Protection to adopt regulations that set this speed limit at ten miles per hour. These regulations must be implemented by April 1, 2026, and will be developed in accordance with the provisions of chapter 54 of the general statutes.

This legislation introduces new legal language that specifies the speed limit and the timeline for regulation adoption, but does not delete any existing legal language. The bill was approved by the Governor on June 10, 2025, marking a significant step towards ensuring safety and environmental protection on Mashapaug Lake.
