Mariaville Lake, NY

Mariaville Lake is a Schenectady County census-designated place in the town of Duanesburg, named for the lake that gives the hamlet its shape. The lake is about 200 acres and 1.5 miles long, reaches into neighboring Princetown, and sits in the Mohawk River basin. Duanesburg’s planning documents treat the shoreline as a lake district, with the Mariaville Lake Sewer District serving properties around the water. The Mariaville Civic Association takes part in lake monitoring through New York’s CSLAP program, so water management sits on the local calendar alongside roads and houses. Mariaville Lake is a lake-centered hamlet where the shoreline, sewer district, and civic association draw the map.
