Upper Narragansett Bay Fish Passage: Case Studies in Connectivity Restoration

Abstract

Connectivity is an essential consideration and attribute of most aquatic ecosystem restoration projects. Fish passage projects provide one of the most direct demonstrations of the importance of connectivity for imperiled migratory taxa. The U.S. Army Corps of Engineers (USACE) New England District (NAE) completed two efforts in the upper Narragansett Bay, Rhode Island that demonstrate many of the obstacles, or constraints, associated with connectivity restoration of waterways in an urbanized setting. This technical note focuses on two watershed-scale fish passage projects in rivers flowing into the Upper Narragansett Bay and their contribution to the Bays diadromous fish populations. Together, these projects may provide a substantial increase in the quality and quantity of fish and wildlife resources by reducing the impacts of dams on fish passage connectivity. First is an overview of these ecosystem restoration projects. Then, the key lessons learned are synthesized from these projects which can be transferred to fish passage and connectivity restoration projects nationwide.
