Providing Fish Passage at the Middle Fork Nooksack River Diversion Dam
In 2002, the City of Bellingham, WA began seeking a solution to the dilemma about how to restore fish passage at the site of their diversion dam on the Middle Fork, Nooksack River. The problem was created when the diversion dam was constructed in 1960-61 with no provisions for fish passage. Different options for resolving the fish passage problem were considered over the intervening years by the City and are discussed in this paper. These options included the addition of a fish ladder to the dam, and a river engineering concept that would have allowed the dam to be partially removed and river water diverted through a new intake structure. These previous concepts failed for various technical feasibility and economic reasons. The City's search for a feasible solution has now turned to consideration of a siphon-based diversion system coupled with a partial removal of the dam. The current status of the siphon option is discussed.
