Merrimack pike and crappie holding despite low, cooling water
The Contoocook River gauge (USGS 01091000), a direct Merrimack tributary, read 52°F on a lean 15.8 cfs this morning, in line with what Roger Aziz Jr. described this week for the Merrimack itself: water levels running low, same as most ponds, lakes and rivers across the Northeast Wildlife District right now. He fished the river anyway and did fine, landing five northern pike and a handful of crappies in a single outing, per The Fisherman — New England Freshwater. That's a useful read for anglers eyeing Merrimack and Winnipesaukee water this week: low, cooling flow hasn't shut fish down, it's just concentrating them.

With the river gauge sitting in the low 50s and flow thin, expect water to keep sliding through the fall transition over the next several days rather than spike back up. Pike and crappie activity should hold steady to improve as that cooling continues and baitfish groups get pushed tighter by the low flow, the exact pattern Aziz described working the Merrimack this past week.
A waxing gibbous moon builds toward full over the coming days, worth factoring into early-morning and evening windows if you're planning a weekend trip. With levels this low, working deeper pools and current seams where pike and crappie are stacking is a better bet than spreading out across skinnier stretches.
Context
Late September puts NH's freshwater fisheries squarely in the early fall transition: cooling water, thinning summer flows, and fish beginning to group up ahead of the seasonal shift. Low river levels this time of year are typical rather than a red flag for this region, and the pike/crappie activity described on the Merrimack tracks with what's expected as that transition gets underway.
