Highland Ponds and the DAR State Forest are great places to visit and I have been there often.
Lower Highland Lake was made by the CCC in the 1930s. The dam was a 1840 mill dam that was improved. It was owned by the Hampshire Water Power Company.
Upper Highland Lake has a mill dam from 1873. It was renovated by the CCC also.
The DAR State Forest was made in 1929 when the DAR gave the state a forest. The CCC built Moore Hill Road in 1933. The State Forest is in both Goshen and in Ashfield.
In DAR State Forest at Twinning Brook there is a dam system. There is a spillway there too.
