Merrimack River is a public river in Merrimack County and Hillsborough County, New Hampshire, managed by State of New Hampshire (public / navigable water). You can fish it on a New Hampshire fishing licence; bank access is at bridge crossings, NHFG access points and public parks. New Hampshire riverbeds are private property up to the ordinary high-water mark except on a few federally-declared-navigable reaches, so wading or bank fishing away from a public access point needs the landowner's permission. Public access confirmed via marquee water.
The Merrimack River — New Hampshire's largest river entirely within New England, running from the White Mountains through Manchester and Nashua to Massachusetts. Smallmouth and largemouth bass, chain pickerel, and a restored American shad run.
It runs roughly 93 miles through the Merrimack Valley region. Anglers here mostly fish for smallmouth bass, largemouth bass, chain pickerel, american shad; yellow perch are also on record. Live flow and gauge height come from the Merrimack River At Concord, Nh USGS station shown below. The nearest other mapped waters on PiscaMaps are Goldfish Pond and Dorrs Pond.

Night fishing: New Hampshire allows fishing 24 hours a day on most waters; some designated trout ponds are restricted to daylight hours seasonally — check the current NHFG fishing digest for this water.
Boats: Lake Winnipesaukee, Squam, Sunapee and the other big lakes take full-size boats with developed ramps; many smaller ponds have only a hand-carry or cartop access. NH requires boater education for personal watercraft and for operators born after 1 Jan 1988.
Bank & bivvy camping: Camp at New Hampshire state parks (several on Winnipesaukee, Squam and the Connecticut Lakes) and White Mountain National Forest campgrounds along the trout streams.
Tackle: Statewide bass limit is usually 4 (with a closed season in spring on some waters); trout limits vary by water and many streams are catch-and-release or artificial-lures-only; pickerel, perch and horned pout are generous. Check the current NHFG fishing digest for this specific water.
