Palgrave Dam

Originally constructed in the 1850’s but TRCA did not acquire the dam until 1979 where they carried out rehabilitation works in 1983. When the dam was created in the 1950’s it also created the Palgrave pond located on the east side of highway 50. Although no longer in operation, the dam and the pond have remained intact to preserve the dam for its local historical and heritage values.
