Agnew Lake (Ontario)

Agnew Lake is a lake on the Spanish River in the Sudbury District, Ontario, Canada. Its area is 2940 ha and its shoreline is 210 km long.

The lake is located primarily in the municipalities of Sables-Spanish Rivers, Baldwin and Nairn and Hyman, although its easternmost end enters the city limits of Greater Sudbury near High Falls. It is formed by the 353.57 m long and 44.50 m high Big Eddy Dam, built in 1920, and serves as the reservoir for several hydroelectric power stations downstream.

The lake has been the site of varied mining activity, including drilling for diamonds in the earlier half of the 20th century and for uranium from 1977 to 1983 at Agnew Lake Mine.

The lake was named after John Lyons Agnew, who became president and general manager of INCO in 1921.
