Lake Champlain smallmouth peaking as summer bass and catfish patterns lock in

What's biting

What's next

With the full moon cresting tonight, the most productive windows over the next several days will be the final two hours before dark and the first hour after sunrise. Bass on Lake Champlain — both smallmouth and largemouth — tend to push shallower and feed more aggressively under a full moon, ambushing prey once the sun drops. Topwater presentations are the play through the weekend: Whopper Ploppers, walking baits, and surface frogs along weed edges and rocky shorelines should produce into the early days of July.

As water temperatures continue their seasonal climb, midday will push smallmouth deeper onto rocky ledges, points, and submerged structure in the 12-to-20-foot range. Per The Fisherman — New England Freshwater, smallmouth around bigwater structure are a consistent late-June theme across New England reservoirs and lakes; jigs and drop-shot rigs become increasingly productive once the sun is high. Save topwater for the low-light shoulders and let the structure game carry the midday hours.

On the Connecticut River, the catfish transition noted by Fishin' Factory 3 should hold through the coming weeks. Cut bait and nightcrawlers fished near deep holes and undercut banks in slower current are the traditional producers. The full moon phase often intensifies catfish activity — tonight and the nights immediately following can be strong for river anglers willing to fish after dark. Bowfin are a legitimate bonus target on the Connecticut River right now; regional intel from The Fisherman — New England Freshwater confirms them active alongside catfish and willing to take a wide range of presentations.

Trout anglers should plan around the heat. Summer conditions have pushed trout into slow mode region-wide, and Vermont's lower-elevation waters are no exception by late June. Cold-water tributary mouths offer the best shot if trout are the goal. Watch for afternoon thunderstorms — common in late June across Vermont — as a post-storm cool-down can spark a strong feeding response from bass and catfish alike, often within an hour of clearing skies.

Context

Late June marks a consistent turning point for both of Vermont's flagship freshwater systems, and the picture this week reads as on schedule rather than early or late.

On Lake Champlain, smallmouth bass have typically completed spawning by mid-June. The final week of the month and the first weeks of July represent a prime post-spawn feeding window — fish that were protecting beds are now actively chasing prey, and the combination of warming surface temperatures and long daylight hours concentrates baitfish in the shallows, pulling bass with them. The full moon on June 28 lands at a historically favorable time: the June full moon is widely regarded as one of the top smallmouth nights of the year on large northern lakes like Champlain.

The Connecticut River's shad run wrapping by late June is exactly on schedule. American shad push upriver into Vermont's reach through May and early June, and the run concludes by month's end in most years. The pivot to channel catfish and bowfin that Fishin' Factory 3 describes is the expected seasonal hand-off — not an anomaly, just the calendar turning.

MidCurrent notes the Battenkill Fly Fishing and Arts Festival in Arlington, Vermont drew strong attendance this spring, reflecting continued regional enthusiasm for Vermont trout waters. That interest is well-founded, but late June is a transitional month for trout across the state: water temperatures on many Vermont rivers climb above the comfortable range for wild browns by mid-afternoon. The premier trout fishing the Battenkill and similar cold-water streams are known for tends to concentrate in the early morning hours during summer.

No comparative gauge or buoy data was available for this report, so a precise year-over-year flow or temperature comparison is not possible. Based on the regional angler intel available, late-June conditions appear consistent with a typical Vermont early summer — bass are the headline, catfish are the river sleeper, and trout fishing calls for an early alarm.
