Spring shad run underway as Vermont's big-water bass approach spawn

What's Biting

What's Next

With the Connecticut River sitting at low, clear levels, the next two to three days should hold steady on the upper Vermont reach absent any significant rain in the upper watershed. That gin-clear, slow-moving water is a double-edged setup: sight-fishing opportunities improve, but fish get spookier. Drop down a line size, slow your approach on the bank, and target the deep seams, pool tails, and channel ledges where fish stack under low-flow conditions.

**American shad** are the most time-sensitive target right now. The Fisherman — New England Freshwater's Fishin' Factory 3 report from Middletown, Connecticut confirms the migration is fully underway on the lower river this week. Shad move through Vermont's Connecticut River reach in mid-to-late May, typically arriving in concentrated feeding waves that hit hard on light jigs and small shad darts before pushing further upriver. Low flows like those registering now can actually concentrate fish in the main-channel seams — an advantage for wading anglers who know where the drop-offs are. Dawn and early morning are the prime windows; watch for surface boils near run tails and rocky ledges.

**Smallmouth bass** should be the other priority over the coming weekend. The Fisherman — New England Freshwater's Fisherman's World notes that New England bass action is "steadily improving" as water temperatures climb, with live shiners performing best across the region and Keitech swimbaits producing well on artificials. Vermont smallmouth typically run one to two weeks behind their southern Connecticut counterparts in seasonal temperature progression — meaning while lower-river largemouth are already deep in spawn, Vermont's river smallmouth are likely still in active prespawn or early-spawn mode, an aggressive and highly catchable phase. The waxing crescent moon building toward first quarter over the coming week should intensify shallow-water feeding at dawn and dusk, particularly near current breaks adjacent to gravelly flats.

On Lake Champlain, no source-backed reports came through this cycle. Seasonally, mid-May is when walleye move from spawning shallows to rocky structure and northern pike begin recovering post-spawn along weed edges. As lake temperatures approach the upper 50s, largemouth action in the protected northern bays typically accelerates. Focus on the transition zones — points and drop-offs adjacent to spawning flats — as fish begin establishing early-summer patterns.

One weather-driven variable worth watching: any significant rain event in the upper Connecticut watershed could bump the gauge quickly from its current low baseline, temporarily stirring sediment and pushing fish to slack-water edges. Check USGS gauge 01135300 before heading out and adjust accordingly.

Context

Mid-May is a seasonal hinge point for Vermont's big-water fisheries, and the current Connecticut River readings are worth context. Flows on the upper Connecticut typically range from several hundred to well over a thousand cfs during active spring snowmelt in April and early May. The current 109 cfs reading (USGS gauge 01135300) sits at the low end of what would normally be expected for this date, suggesting either a light winter snowpack, an early melt peak, or a dry stretch heading into late spring. For anglers, that translates to one important shift: the transition window between runoff chaos and summer low-water that defines prime May conditions on the upper river has arrived ahead of schedule. Early low flows can be a gift — better visibility, more predictable fish location in deeper channel structure — but they also accelerate warming, which may compress the cold-water window for trout and landlocked salmon before summer stratification fully locks in on the lake.

For Lake Champlain specifically, no angler-sourced reports arrived this cycle to allow a direct comparison to prior seasons. The honest read, absent conflicting data, is that the lake appears to be tracking close to seasonal norms — nothing in the available sources suggests an unusual year on Champlain. Mid-May historically marks the transition from the landlocked salmon and lake trout spring season to the prime walleye and bass window, and that trajectory appears intact.

The broader New England freshwater picture, as reported by The Fisherman — New England Freshwater, suggests a season progressing at least on-schedule: trout stocking is underway (the Salmon River in Connecticut was stocked May 13), bass action is improving steadily across the region, and the shad migration is running strong on the lower Connecticut. MidCurrent's coverage of the Battenkill Fly Fishing and Arts Festival in Arlington, Vermont in late April and early May provides a qualitative signal that the 2026 spring season in Vermont did not get off to a troubled start — the fly-fishing community considered conditions worth celebrating in the field.
