Shad run pushing north on the Connecticut River ahead of June

What's Biting

What's Next

The full moon falling at month's end sets up the strongest low-light feeding windows of the early season. On Lake Champlain, expect the most aggressive smallmouth activity at dawn and dusk along rocky shorelines, boulder flats, and deep structure transitions. Tactical Bassin notes that post-spawn bass in northern lakes are responding to chatterbaits and swimbaits on isolated offshore structure, with finesse options like the Neko rig filling in during the midday slowdown. As surface temperatures build through early June, topwater presentations along weed edges and rocky points will come increasingly into play on calm mornings — the full moon can also push big fish shallow overnight, so early risers this weekend may find bass closer to structure than expected.

On the Connecticut River, the shad run is the dominant story and timing is right. The Fisherman — New England Freshwater places active fish in the Holyoke, Massachusetts stretch right now — Vermont's section is next in the queue as temperatures warm and fish push upstream. Target deep pools and inside current seams where migrating shad stage to rest. Small darts and shad rigs are the traditional producers for this species along the Connecticut River corridor; lighter presentations fished through current breaks can also draw strikes as fish become more active. White perch are arriving in the mix, per the same source, on sandworms — worth keeping a rod rigged for incidental catches. Verify current harvest rules with Vermont Fish and Wildlife before keeping shad.

Trout fishing offers a quieter alternative this week. Per The Fisherman — New England Freshwater, trout are available throughout the river corridor but seeing lighter pressure as the shad and bass bites dominate. MidCurrent's recent fly-tying roundup highlights high-floating attractor dries for fast-water riffles and midge or nymph patterns for clear, pressured tailrace-style pools — both applicable to Vermont river trout right now. At 155 cfs, wading access should remain favorable. Monitor the forecast for the late-day thunderstorms common in late May across the region; a runoff pulse can temporarily cloud the river and push trout off their feeding lies.

Looking into the first week of June: if flows hold steady or ease further, migrating shad should concentrate in predictable holding water and become easier to target methodically. Any sustained rain event could briefly push the river up and scatter fish — plan around stable windows when possible.

Context

Late May marks the leading edge of shad season for Vermont's section of the Connecticut River. American shad are anadromous fish that spawn progressively further upstream as the season advances — southern New England rivers see peak runs through April and early May, Massachusetts reaches like Holyoke are active now per The Fisherman — New England Freshwater, and Vermont's upper corridor historically sees its peak shad action in June. The 2026 run appears to be tracking on a typical schedule, with the geographic progression unfolding as expected.

The river's current reading of 155 cfs is consistent with normal late-May conditions following the spring freshet. Vermont's Connecticut River headwaters typically crest with snowmelt in April; by the end of May, flows have usually settled into the low-to-moderate range that characterizes early summer. Nothing in this week's gauge data suggests the river is running notably out of step with seasonal norms.

On Lake Champlain, late May is a reliable transition point. Smallmouth bass typically complete their spawn when water temperatures climb into the mid-50s to low 60s°F, placing the post-spawn recovery and early aggressive feeding phase squarely in the final week of May — right where Tactical Bassin's current intel on northern lake bass behavior lines up. Walleye, another Champlain staple, finish spawning earlier in spring and are generally well into summer feeding patterns by this date. MidCurrent notes that the Battenkill Fly Fishing and Arts Festival recently held its fifth annual event in Arlington, Vermont, reflecting the enduring culture around Vermont trout fishing as the region heads into summer — a reminder that the state's stream fishery draws dedicated fly anglers even when the shad and bass bites are competing for attention.

One honest caveat: no Vermont-specific tackle shop, guide, or state agency report appeared in this week's data. The analysis draws on adjacent-region reports from The Fisherman — New England Freshwater and general seasonal patterns for this watershed. Vermont conditions typically lag southern New England by two to three weeks, a lag already factored into the outlook above.
