In particular, more state and federal fund<strong>in</strong>g is needed for <strong>the</strong> designand construction of dispersal barriers that can discourage <strong>in</strong>vasive species from enter<strong>in</strong>g<strong>the</strong> lake via <strong>the</strong> Champla<strong>in</strong> and Chambly Canals.• Vermont, New York and Quebec should adopt consistent <strong>in</strong>vasive species policiesand enforcement that <strong>in</strong>clude stronger bait bucket laws, live-well clean<strong>in</strong>g programs,eng<strong>in</strong>e-flush<strong>in</strong>g prohibitions, and prohibitions on <strong>in</strong>troduction of nonnative species.• Fund and streng<strong>the</strong>n efforts to educate <strong>the</strong> public about <strong>the</strong> causes and consequencesof <strong>in</strong>vasive species <strong>in</strong>troductions, especially by expand<strong>in</strong>g monitor<strong>in</strong>g and educationalactivities of lake steward programs at boat launches.• More effective federal regulation is needed to reduce airborne mercury deposition <strong>in</strong><strong>the</strong> Nor<strong>the</strong>ast.• More efforts are needed at all levels to reduce CO2 emissions.38
