Mono Pond State Park Reserve in Columbia, Connecticut, became part of the state park system in 2008. Covering 218 acres and managed by the Connecticut Department of Energy and Environmental Protection, it surrounds the 113-acre Mono Pond, a notably shallow body of water that averages about 3.5 feet deep, with deeper water near the dam. The reserve’s open water and shoreline give it a quiet, low-key character. Its significance lies in preserving this pond-centered landscape while providing outdoor recreation, including fishing, hiking, picnicking, cross-country skiing, bow hunting, and boating for non-motorized craft and small motorized boats.
