Abstract:

This report provides information on the potential construction of a weir on Morpion Stream in order to reduce its suitability as a spawning ground for sea lamprey and consequently reduce the sea lamprey population in Lake Champlain. The four potential weir designs considered were based on the determination of two prior reports (Walrath and Swiney, 2001 & Dean and Zerrenner, 2001), which determined that the construction of an adjustable-crest weir on Morpion Stream was the most economically feasible and ecologically acceptable method for reducing the sea lamprey population of the Pike River watershed. This report provides information on the rationale for a weir, the plans for its construction, the means of its operation, its potential impacts on the native flora and fauna, and its anticipated impact on sea lamprey reproduction. All four of the potential designs considered trap fish and lamprey that can then be released upstream or removed. All of the designs proposed would only be implemented annually during the three month lamprey spawning period so as to have a minimal impact on non-target species and the river ecosystem.   This report concludes that one of the wier designs would enable the Lake Champlain Fish and Wildlife Management Cooperative to eliminate the significant sea lamprey population contribution Morpion Stream currently provides to Lake Champlain.
