  • River Herring and Shad Monitoring
  • Winnicut River Dam Removal Project - The Winnicut River Dam was a head-of-tide dam owned by NH Fish and Game with an associated Canadian step-weir fish ladder. Due to dam safety inspections and fish passage issues for anadromous fish, a feasibility study was conducted to determine the best course of action to improve fish passage and general ecological functions of a natural flowing river system and tributary to Great Bay. The dam removal, a new fishway, and related stabilization was conducted between 2009 and 2011 with funds from Natural Resources Conservation Service, NOAA Fisheries, ARRA, NH Fish & Game Department, NH Department of Environmental Services, NH-Coastal Conservation Association, NH Charitable Foundation, The Town of Greenland, and The State Conservation Committee’s Conservation Grant Program. Currently, work continues on improving diadromous fish passage and habitat within the Winnicut River.
