Grand Lake Matagamon or Matagamon Lake is a reservoir on the East Branch, impounded by Grand Lake Dam. The dam was built at the outlet of First Lake, and flooded vast expanses of low-lying land extending upstream to include Second Lake.
The shallow water habitat created by the dam is more suitable for yellow perch, fallfish, and longnose sucker rather than for trout.[5]
