Lake Arrowhead, also known as Arrowhead Mountain Lake, is home to a variety of fish including smallmouth bass, panfish, pickerel, northern pike and rainbow trout. It was formed as a reservoir with a hydro dam at its southern end. However, the Town of Milton sources its drinking water from Lake Champlain.
