The Sacandaga River is a river in the northern part of New York in the United States. Its name comes from the Native American Sa-chen-da'-ga, meaning "overflowed lands". The Sacandaga River is a tributary of the Hudson River, flowing into it at Hadley, at the border of Saratoga County and Warren County. River course 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. Near the town boundary between Wells and Lake Pleasant, the river flows into a series of ponds. The Sacandaga River course takes a steep path flowing over a series of waterfalls including Christine Falls, Austin Falls and Auger Falls. The East Branch joins the trunk stream in the town of Wells. After flowing through Wells, the river enters Lake Algonquin, a manmade impoundment constructed in the 1920s to stimulate the community's tourism industry. The East Branch goes through Johnsburg in Warren County and flows parallel to, in part, NY Route 8, passing the communities of Oregon in Johnsburg and Griffin in the town of Wells. The Sacandaga flows out of Lake Algonquin into a hydro-electric plant and follows a course of rapids to Great Sacandaga Lake through the towns of Hope and Benson. In that area, it connects with Groff Creek. Then it enters the Great Sacandaga Lake in the village of Northville, which it flows through the lake to the Conklingville Dam. Which then it enters the town of Hadley, where it ends at the Hudson River. Downstream of Stewart's Dam in Hadley, recreational releases are held by Brookfield Energy, creating a two-mile Class II whitewater run to the Hudson River for local paddlers. Hydrology The United States Geological Survey (USGS) maintains a few stream gauges along Sacandaga River. The one station located upstream from Hope, had a maximum discharge of per second on March 27, 1913, and a minimum discharge of
