Champlain smallmouth window holds as water sits near 65°F
USGS gauge 04294500 near Lake Champlain read 65°F this morning, right in the zone smallmouth and landlocked salmon feed actively through as summer eases into fall. No flow reading came through on this check, but the temp alone points to fish still shallow and willing rather than pushed deep.

With water still holding in the mid-60s, expect smallmouth to keep working rocky points, drop-offs and current seams through the week; landlocked salmon should continue following baitfish as surface temps trend cooler into early fall. The First Quarter moon this week means moderate tidal-style current pulses on connected waterways, worth timing early-morning and dusk trips around. No fresh angler reports came in for this stretch of Champlain this cycle, so treat the temp read as the best available signal and adjust presentations deeper if mornings turn noticeably colder over the next few days.
Context
Mid-to-upper 60s water temp in late September is typical for Lake Champlain, sitting at the tail end of the warm-water period before fall turnover pushes smallmouth and salmon into transitional patterns. This is an on-schedule seasonal read for the region, not an early or late shift.
