The Sacandaga River's headwaters north of Great Sacandaga Lake begin in the town of Lake Pleasant. From Lake Pleasant, the river follows a short moving course or path known as the Sacandaga Outlet (under New York Route 8) into Lake Pleasant. The Sacandaga River drains Lake Pleasant at a location next to the public beach in the village of Speculator. The river then follows a winding path through some wetlands and various ecosystems through the county. In Speculator, the Sacandaga River Community Park was built by local volunteers and has a number of boardwalks and pathways that follow the course of the river.
