What is the current condition of the dam?


The Orland Village Dam is the lowermost (most seaward) dam on the Narramissic River, which is also known as the Eastern or Orland River. There is another dam at the “Upper Falls,” near the outlet of Alamoosook Lake, and another at the outlet of Toddy Pond. Both upper dams have working fishways.

The current Orland Village Dam was built in the 1930s by the Maine Seaboard Paper Company to create a water supply for the paper mill in Bucksport. However, it was never used for this purpose because the next upstream dam, at the outlet of Alamoosook Lake, proved to be more efficient.

The dam is constructed of wooden timbers filled with rock (“cribwork”), with a small amount of concrete added later in an attempt to patch some internal leaks. This type of construction is not ideal for tidal/saltwater conditions currently being experienced, a situation expected to get worse over time with accelerating rates of sea-level rise, as the dam is already regularly overtopped by monthly high tides and is not a complete barrier to the tidal exchange of salt and fresh water.

Annual maintenance costs are estimated at $7,000; this does not include damage from storms or other disasters, which have led to more costly repairs in the past.

Verso made $83,845 in repairs to the dam in 1985; the dam was rebuilt again after it was damaged by a storm-driven tidal surge in January 1994, at a cost of approximately $93,855. Other repairs occurred during the 1990s, including over $10,000 spent on the fish ladders. In 2010 the Town of Orland agreed to take ownership of the dam from Verso when the paper company indicated that they would abandon and possibly remove the dam if the town did not take ownership. Verso provided up to $5,000 for minor repairs on the dam.
