ESSEX, CT—Work has started along the Falls River on a fishway that will benefit such migratory fish as alewife and blueback herring, as well as migrating American eel and other resident fish.
The work at the privately owned Tiley-Pratt dam will open the way for fish to access an additional 2.5 miles of river, as well as a half-acre pond above the dam. Located at a former mill site, the dam has a stone-wall lined channel that will be modified with a rocky ramp and four stone weirs. Falls River is part of the Connecticut River system.
Connecticut Department of Energy & Environmental Protection staff is assisting with construction. The Essex Land Trust and the dam’s owner are also providing financial and other support for the project, which is expected to be completed during August.
“Connecticut streams are riddled with small dams that have big impacts. Reconnecting rivers by removing dams and building fishways improves river health by increasing species diversity and providing fish access to more and varied habitat.” said Sally Harold, director river restoration and fish passage for The Nature Conservancy in Connecticut.
The Conservancy is working with the Essex Land Trust to develop and install an educational sign describing fish passage and river restoration strategies at the land trust’s nearby Tiley-Pratt Preserve.
“The east bank of Tiley-Pratt Pond is one of six Essex Land Trust preserves which border the Falls River, the ecological and historical lifeline linking together the villages of Essex,” said Bob Nussbaum, past president and current vice president, of the Essex Land Trust, which also has committed $2,000 towards the gravel to be used in constructing the fishway. “We are very excited to participate in this project to improve the river habitat and restore connectivity for migratory river species.”
The Tiley-Pratt dam project also is supported by an $85,000 grant award from The National Fish and Wildlife Foundations’ Long Island Sound Futures Fund.
Portions of the Long Island Sound Futures Fund grant also will support work at Coleytown dam on the Aspetuck River in Westport and a dam on Beaver Lake in Oyster Bay, Long Island. The grant required a Conservancy match of almost $60,000, secured through donor support and in-kind contributions.
