Damariscotta Mills Fish Ladder Restoration

Welcome to historic Damariscotta Mills, Maine – home to one of Maine’s oldest and most productive alewife fisheries. The stone fish ladder that is the centerpiece of Damariscotta Mills was constructed in 1807 by the Towns of Nobleboro and Newcastle because, for nearly a century, mills blocked access for fish to the freshwater falls. In 2007, after two centuries of use, the fish ladder was in poor condition so a restoration project was initiated by a strong community group working with the Towns of Nobleboro and Newcastle and the Nobleboro Historical Society.

Restoration of the fish ladder has had a signficant positive impact on the health of the Damariscotta River alewife stocks. Alewives are an important part of the food chain and they contribute to the health of the marine environment and to the lakes and streams where the fish spawn. In the spring, a few harvested alewives are smoked as “people food” but most serve as a source of fresh bait for local lobstermen. The Towns of Newcastle and Nobleboro have harvested alewives since the 1700s and, by balancing conservation and economic goals, they have carefully tended the Damariscotta River alewife stocks. Today, all funds received for harvested alewives are spent to maintain and restore the fish ladder and harvesting area.

The 2021 run is over…and it was big!

The hot weather put an end to this years alewife run, which was already winding down. The final count of alewives getting into Damariscotta Lake to spawn is 1,047,918! Now that’s a lot of fish!

The fish came back!

After a cold and wet Memorial Day weekend, when the alewives backed out almost entirely, sunshine and warmth this week brought them back into the fish ladder. The run is definitely slowing but there are still fish to see. Yesterday we observed a seal swimming along the entrance to the fish ladder. He (or she) […]

The Alewives have slowed down!

Cold and rainy weather has taken a toll on the alewife run. This morning, there are few to no new alewives in the fish ladder and not many throughout the fish ladder. Sad to see after the huge masses of fish of the last few weeks. We won’t know until the weather warms whether or […]

The alewives are running well!

After a week ‘s break, another school of alewives entered the fish ladder yesterday. Alewives have been flipping in Great Salt Bay in the evenings for a week so it seems likely that the run has begun in earnest. The sky is busy with birds— Osprey diving to catch fish and eagles among them. It’s […]
