Portobello Creek National Wildlife Area, New Brunswick - Coldspring Lead Wetland Naturalization Project

Ducks Unlimited Canada proposes to naturalize the freshwater Coldspring Lead impoundment that was constructed in 1992. By naturalizing this impoundment, the proponent proposes to restore the original hydrology connecting of Coldspring Lead Brook which flows into the Portobello stream. The scope of the project will include removal of the water control structure that is present and breach the berm in two locations to return this project site to its natural pre-construction (1992) state. These breach's will be strategically placed where preexisting tributaries were present in historical imagery. To reach project location with machinery, small road improvements will have to be made, along with beaver removal as they have flooded out the access road with dams. The breaches will be designed to minimize excessive erosion. Dyke material removed to excavate the breaches will be placed back into its original location along the toe of the dyke into the borrow pit. The total area of this project is roughly 70 acres

The scope of this project includes removal of incompatible vegetation along the extent of the existing lengths of dyke within segments 2-3 and 3-1. The dykes will be levelled and re-topped with glacial till from a local source. The proposed work will be completed during the winter when frozen ground conditions exist, and disturbance to migratory birds
