Ragged Lake (Maine)

Ragged Lake is the source of Ragged Stream in the North Maine Woods. The original lake in Maine range 13 townships 2 and 3 was flooded and expanded by a concrete dam built 2 mi downstream. The resulting reservoir created a large shallow area with two basins deeper than 30 ft. Summer dissolved oxygen concentrations are low in the deep basins. Conditions have become more favorable for fallfish and longnose sucker than for the native brook trout. Bear Brook enters the south end of the lake, and supports a spawning run of rainbow smelt. Ragged Stream flows 4 mi from the dam at the south end of Ragged Lake into the Caribou Lake arm of Chesuncook Lake.
