Merrimack stripers running strong as NH freshwater season hits stride

What's Biting

What's Next

The 66.2 cfs flow at USGS gauge 01073500 heading into the weekend tells an important story: the Merrimack is running lean and clear, which compresses the productive bite window to low-light periods. Midday fishing on more exposed, shallow runs will be tough. Expect the better striper action to cluster around dawn and dusk, working eel-like soft plastics and live eels through deeper channel bends and pool tails.

The shift worth watching is the Lawrence area slowdown reported by Surfland Bait in The Fisherman this week. When upriver fish begin dropping back, anglers fishing the NH reaches have a window to intercept them in transitional water before they push back toward tidal stretches. Current seams, channel ledges, and the tail ends of deeper pools in the lower NH Merrimack corridor are the priority targets over the next few days.

The waning crescent moon this weekend brings reduced tidal pull and softer ambient light. That generally means less current-triggered feeding on the tidal section, but better low-light window feeding for stripers overall. First-light sessions through Saturday are the priority, leaning into structure fishing rather than counting on a strong current feed.

On Lake Winnipesaukee, the next few days represent a prime early-summer transition window for smallmouth and largemouth. Wired 2 Fish's current summer bass coverage describes the pattern directly: fish are shallow and chasing bait through the early morning hours, then sliding to deeper structure and rock ledges as the sun builds heat. Rocky points, channel breaks, and weed edges fished from first light through 8 a.m. are the topwater play. Swing head jigs and crankbaits on deeper rock structure, consistent with techniques highlighted by Tactical Bassin for early-summer bass, become the midday approach.

The shad uptick noted by Dave Anderson in The Fisherman is worth watching as well. Active shad keep stripers in the river longer and more aggressively positioned. Any continued shad presence through the weekend extends the productive striper window in the NH watershed. Plan your alarm for the 5 to 8 a.m. window across both venues and check the local forecast before launching.

Context

Mid-June on the Merrimack and Lake Winnipesaukee is historically one of the more dynamic windows of the NH freshwater season. The Merrimack's annual striper migration typically peaks in May through mid-June, with fish pushing well into NH waters before summer heat and low flows turn the upstream reaches off. The 66.2 cfs USGS reading is consistent with the low, stable flow typical of this period after spring runoff clears. Those conditions tend to shift striper behavior from aggressive upriver pursuit toward a more holding-and-ambush posture in deep pools and shaded runs.

The Lawrence-area slowdown followed by downstream redistribution, as reported by Surfland Bait through The Fisherman, tracks the expected mid-June pattern. When the upper Merrimack bite fades, the NH reaches historically pick up the momentum for another few weeks before warm water pushes fish back toward tidal territory for good. The shad uptick is also consistent with the species' late push into NH waters through early summer.

On Winnipesaukee, June is the threshold month between the cold-water spring bite and the full summer warmwater pattern. Smallmouth bass are likely wrapping their post-spawn recovery phase and entering a hungry, active period on the lake's rocky structure. Largemouth are transitioning to shallow weed edges and protected coves as surface temperatures climb. These patterns align with the seasonal arc described in Wired 2 Fish coverage, though no NH lake-specific reports appeared in this week's intel feeds to confirm local conditions directly.

No direct comparative data from prior June seasons is available in this week's intel. Based on the data in hand, the season appears broadly on schedule: a transitioning Merrimack striper run, low early-summer flows, and bass across both the river and Winnipesaukee moving into predictable summer-mode behavior.
