Aquatic Connectivity

100% connectivity in a watershed means that the small upland tributaries are all connected to the mainstem of the river.  A connected watershed is one in which water, nutrients, sediment, fish and other aquatic organisms can all freely move back and forth between habitats.  Connectivity has been broken in most New England watersheds for many generations due to the building of lake outlet dams, mill dams, roads with improperly sized culverts and bridges.  Culverts were originally used to move water to keep roads dry, not to allow for natural stream processes to occur.  Many of these poorly sized culverts that exist on tribal trust lands are being updated. In addition, three lake outlets on tribal lands within the Penobscot River will be reconnected by the building of nature-like fishways within the mainstem Penobscot river and will allow for the restoration of alewives and shad to tribal waters.
