Champlain's bass spawn in June. Smallmouths can be found on rocky shores and shoals. You'll find largemouths in weedy, shallow bays. Tube jigs, spinnerbaits and deep-running crankbaits will entice bass to bite, particularly if the fish can be found on their spawning beds. As for fly selection, during the spawn in June bass are most responsive to poppers, mice and muskrats. Almost any place except deep, cold water is a good place to find bass in Lake Champlain. Concentrate on humps, reefs, weed beds, drop-offs and shorelines. Expect to catch bass in the 3-pound range.
