Branch River Fishing Guides and Conditions, Rhode Island

About the Branch River

The Branch River is formed at Forestdale where the Clear River and the Chepachet River come together, and it runs about six miles east to meet the Blackstone at Woonsocket. The USGS gauge sits at Forestdale near that junction and watches roughly ninety-one square miles of northern Rhode Island. It reports discharge and stage and carries no temperature series, which matters more here than on a bigger river: this is a small, low-gradient New England stream whose trout fishing is governed almost entirely by how warm it gets in July and August.

Rhode Island’s Division of Fish and Wildlife stocks the Branch with brown, rainbow and brook trout, and the stocked fishery is the reason most anglers come. The character of the water is classic southern New England mill country. Long flat stretches backed up behind old dam remnants alternate with short, quick riffles and boulder pockets, and the banks carry the second-growth hardwood and the stone foundations of an industrial past that never fully left. The Clear River arm above the confluence is the colder of the two feeders and holds trout later into the summer than the main stem below.

Warmwater species share the river and dominate the slower impoundments. Largemouth bass, chain pickerel, yellow perch and bluegill are common in the flat water, and smallmouth turn up in the faster reaches nearer the Blackstone. In practice the Branch fishes as two rivers in one season: a trout stream in April, May and early June, and a mixed warmwater stream from midsummer onward when the stocked fish have thinned out or moved to the coldest pockets they can find.

Access is straightforward and mostly roadside. This is a wading river; there is no meaningful float. Rhode Island’s freshwater regulations, including the stocked-water rules and the closed period before opening day, apply throughout, and the gauge is the practical tool for deciding whether spring runoff has dropped enough to fish.

Access

Forestdale gauge and dam area - the confluence pool and the flow reference for the river.
Route 102 bridge crossings - several roadside pullouts with short walks to the water.
Clear River arm above Forestdale - the coldest feeder and the best late-season trout holding.
Chepachet River arm - second feeder, smaller and quick to warm.
Branch River Trail and greenway parking - walk-in access along the lower river.
Nasonville area pullouts - riffle and pocket water in the middle reach.
Woonsocket, near the Blackstone confluence - warmwater fishing where the Branch ends.

Seasons

Spring: the core season; stocking, high stable flow and the best trout fishing of the year.
Summer: warms quickly and drops; trout hold only in the coldest pockets and the fishery turns warmwater.
Fall: cooling water and fall stocking in some years revive the trout fishing through October.
Winter: low and cold with ice on the flat water; limited fishing outside mild spells.
