Moving the dam upstream would reduce the watershed area and thus the area of protected land. Reducing the area of protected land could be considered a positive economic factor to Halifax Water as restrictions associated with a protected water supply would no longer apply to the land outside of the "new" watershed area. In addition, land that is no longer protected could be sold and/or developed. consultation with the Department of Fisheries and Oceans (DFO), will set and approve requirements for the fish passage, discharge flow and minimum environmental releases (environmental flow). Reservoir operations were simulated in the HEC-ResSIM software package for various riparian flows using the current actual demand and REGULATORY APPROVAL current approved withdrawal rate.

NSE, in ational limitation to Halifax Water with respect to demand capacity. A wetted perimeter and observation study was developed to prepare site specific riparian flow requirements. Three assessment methods were used to assess appropriate summer maintenance flow: * Observed habitat quality at the flow proposed; * Analysis of wetted perimeter based on cross sections through the river; and * Analysis of historic stream flow and application of standard approaches. Using the results, the riparian flows was recommended for acceptance to the Nova Scotia Environment.
