It's actually pretty good fishing.... Just make sure you don't fish between the NH/MA state border and the Prescott St. Bridge unless you're fly-fishing since it's fly-fishing only in that section.
ok . hows this place for spring fishing., water levels etc.
The Nissitissit River is a 10.5 mile long (16.9 km)[1] river located in southern New Hampshire and northern Massachusetts in the United States. It is a tributary of the Nashua River, itself a tributary of the Merrimack River, which flows to the Gulf of Maine. This river is part of the Nashua River Watershed. The Nissitissit River begins at the outlet of Potanipo Pond in the town of Brookline, New Hampshire. It flows southeast at a very mild gradient, crossing the southwest corner of Hollis, New Hampshire before entering Massachusetts, where it joins the Nashua River in the town of Pepperell. Designated an Outstanding Resource Waters (ORW) in Massachusetts, the Nissitissit River is a high value aquatic riverine ecosystem with high aesthetic quality and great wildlife habitat. Further, the subbasin has the distinction of being the focus of the Squannacook-Nissitissit Rivers Sanctuary Act (MGL 132A:17) passed in 1975 and intended to protect the ORWs of these two river basins from degradation by new discharges of pollution. Streamflow, as in most of New England, has significant seasonal changes. Largely because its headwaters tributary streams drain an area that is heavily forested and little developed — namely, the Badger Hill/Spaulding Brook area in Brookline and Mason, New Hampshire and the Townsend State Forest in Massachusetts — the main stem of the Nissitissit River is a cold, clean, well-oxygenated stream that is frequently cited as prime habitat for native brook trout and five listed rare species. Important habitat areas include: Townsend State Forest, Gulf Brook, Heald Pond, Townsend Hill, Nissitissit Hills, Kimball Farm, and Bancroft Brook Headwaters. Sucker Brook is a cold-water fishery containing native Eastern Brook Trout and is stocked with trout as is Gulf Brook. Mine Brook is also a cold-water fishery. Due to conservation efforts, nearly 50% of the entire length of the Nissitissit River has a 300 foot vegetated buffer strip. There is particularly strong land protection focus in Brookline, NH. Indeed, given its high quality there is consideration of designating New Hampshire Scenic Status to the Nissitissit River.
