Churchill Dam

The Churchill Dam is on Churchill Lake in the Allagash Wilderness Waterway.  It is a non-FERC (Federal Energy Regulatory Commission) dam and is not used to produce hydropower.  The Allagash is located in Piscataquis and Aroostook counties in Maine.  The waterway is 92 miles long and is a popular area for recreational activities, such as canoeing, rafting, and camping.   The Allagash River and the associated lakes are designated 'wild' under the Wild and Scenic Rivers Act.  This designation has created controversy over state management and access to the waterway.
