Shad push north on the Connecticut River as bass and trout hit spring stride
USGS gauge 01135300 logged a flow of 99.4 cfs in Vermont's Connecticut River watershed early May 18 — a moderate spring level that leaves shorelines accessible and wading conditions manageable. The Fisherman — New England Freshwater reports the Connecticut River in its middle reaches is already producing shad and carp, signaling that the head of the annual shad migration is working its way northward toward Vermont's stretches. On Lake Champlain, the new moon (May 18) falls right at the onset of the smallmouth bass spawning window; Tactical Bassin notes that bass pushing into heavy shallow cover during the bluegill spawn respond aggressively to topwater frogs and big swimbaits. MidCurrent recently spotlighted the Battenkill Fly Fishing & Arts Festival in Arlington, Vermont, a clear indicator that trout in the state's tributary drainages are active and drawing anglers out. Walleye are likely wrapping their spring run on Champlain and transitioning toward mid-depth structure.

New to these readings? What do water temp, cfs, tide, and moon phase actually mean for fishing?
What's Biting
American Shad
small darts and shad rigs fished in current seams and pool tails
Smallmouth Bass
topwater frogs and swimbaits along shallow rocky points and wood cover
Brown Trout
caddis and March Brown dry flies on tributary streams during afternoon hatches
Walleye
jigging mid-depth structure breaks as fish move off post-spawn flats
What's Next
Over the next two to three days, moderate flows at 99.4 cfs are unlikely to shift dramatically absent significant rainfall, keeping wade access solid along Connecticut River reaches through Vermont. That stable, receding current is a favorable setup for targeting migrating American shad as they continue pushing northward through the river system.
The shad migration deserves close attention right now. The Fisherman — New England Freshwater reports active shad on the Connecticut River in the Middletown-to-Rocky Hill corridor — the heart of the lower river in Connecticut. At the pace shad typically advance through late spring, the vanguard school could reach Vermont's border reaches within days to a week or two. Anglers should position near current seams, pool tails, and riffle edges with small darts, shad rigs, or light spinners on 6–8 lb fluorocarbon — the same general setup producing fish in the lower river right now.
On Lake Champlain, the new moon (May 18) brings the lunar phase most often associated with heightened shallow-water bass activity. Tactical Bassin describes this stage — overlapping bluegill spawn and new moon — as peak topwater time, with big bass pushing into heavy cover to hunt bait. Topwater frogs, large swimbaits, and reaction baits worked along wood, rock, and emerging weed edges should produce well through the lunar phase window, particularly at dawn and dusk when light levels are low and surface strikes are most aggressive.
Trout anglers across Vermont's tributary drainages — streams feeding both the Connecticut River and Lake Champlain — can expect consistent spring hatches throughout this period. MidCurrent's recent coverage of the Battenkill Fly Fishing & Arts Festival in Arlington signals that the fly fishing community is fully engaged. Caddis emergences and March Brown hatches are typical for Vermont rivers in the third week of May; the new moon may suppress overnight surface feeding, shifting prime hatch activity toward afternoon and early-evening hours.
Walleye are likely transitioning off post-spawn recovery toward summer holding depths on Champlain. Expect slow action on the shallow gravel flats they occupied in April; work mid-depth breaks in the 12–20 foot range with jigging presentations or live bait rigs for fish staging between the spawn and summer structure.
Context
Mid-May is a transitional benchmark for Vermont's two principal freshwater systems. On the Connecticut River, spring snowmelt and runoff typically drive peak flows earlier in April; by the third week of May, levels are usually receding toward early-summer norms — consistent with the 99.4 cfs reading currently at USGS gauge 01135300. This post-peak drop generally marks the window when migrating American shad advance more rapidly northward through the corridor, as receding and clearing water concentrates fish in predictable current seams rather than the flushed, turbid conditions of peak spring flow.
On Lake Champlain, the seasonal calendar puts walleye spawning activity largely complete by mid-May in most years, with fish dispersing from the gravelly shallows and tributary mouths they occupied through April. Smallmouth bass, by contrast, are typically approaching peak spawning intensity in the 55–65°F water-temperature range that mid-May commonly delivers on the lake. Without a current temperature reading — the gauge data returned null for water temp — it is impossible to confirm exactly where fish are in that cycle this year, but the new moon on May 18 aligns with timing that historically correlates with heightened feeding activity during the pre-spawn and spawn transition.
No Vermont-specific outlet reports appear in this week's angler-intel feeds that allow a precise year-over-year comparison. MidCurrent's coverage of the Battenkill Fly Fishing & Arts Festival — held April 30 to May 2 in Arlington this season — is consistent with a normal spring calendar and suggests the 2026 Vermont trout season is tracking on schedule. The Fisherman — New England Freshwater's reporting of active shad and productive trout water on Connecticut River reaches to the south points to a season that is running neither unusually early nor unusually late across the broader New England freshwater corridor.
