This water is stocked on an annual basis, because it lacks sufficient spawning habitat for salmonids. Water quality is good for brown trout, but deeper water develops an oxygen deficiency during the summer. In the early 1980âs, landlocked alewives were introduced by the Maine Department of Inland Fisheries and Wildlife. Brown trout have responded to this new forage, and are doing well in spite of heavy competition from abundant warm water fish populations. Large spring yearling brook trout are also stocked annually to provide anglers with a fish that is less difficult to catch than brown trout.
