The staff at the Northern Maine National Wildlife Refuge Complex are pleased to announce the completion of a collaborative fish passage project at the Moosehorn National Wildlife Refuge. The project is a partnership between the Pleasant Point Passamaquoddy Tribe, Project SHARE and three branches of the U.S. Fish and Wildlife Service. A 24’ wide by 64’ open bottom arch culvert was installed at Popple Flowage (Baring Division) to allow for fish passage from the St. Croix River up through Magurrewock Stream to the base of Vose Pond. The open bottom arch culvert consists of five rock weirs that maintain a predetermined water level in Popple Flowage and allow for natural stream processes to occur. While not only allowing for the upstream migration of alewife, American eel and brook trout; waterfowl and other wetland dependent species will benefit from the innovative design. The entire project from design to installation was completed by U.S. Fish and Wildlife Service staff. The Pleasant Point Passamaquoddy Tribe contributed the metal arch culvert and Project SHARE provided on-site technical construction support.

The Moosehorn NWR was established in 1937 and consists of nearly 30,000 acres of conserved lands in Washington County. The refuge has over 30 miles of hiking trail, contains two federally protected Wilderness Areas, and is free and open to the public from sunrise until sunset. The Refuge actively manages 37 impoundments for the benefit of wildlife. The Moosehorn National Wildlife Refuge is managed as part of the Northern Maine National Wildlife Refuge Complex and includes the Aroostook and Sunkhaze Meadows National Wildlife Refuges.
