Abstract:

This study evaluated alternative measures to allow Atlantic salmon to bypass Townshend and Ball Mountain Lakes, developed a plan to provide the required passage and prepared a report outlining the scope, cost, and impacts of such a plan. Possible alternatives were formulated and evaluated at study team meetings, from which a recommended plan was developed to provide the following 1 construction of a fish barrier and in stream trap downstream of Townshend Lake, 2 modifying the current operation of flow releases at Ball Mountain Lake to provide a 25 foot pool from the end of the last weekend in April to June 1, 3 automating one of the gates to facilitate the maintenance of a 25 foot pool at Ball Mountain Lake, and 4 modifying the outlet structure at Townshend Lake by notching the weir and providing a splash pool at the foot of the outlet weir to allow for downstream passage of smolts. The total project cost is estimated at 1,285,000. This study recommends that the fish passage facilities presented in this report be approved.
