About the South Branch Pawtuxet River
The South Branch is the longer and larger of the two branches that form the Pawtuxet, draining the wooded hills of western Coventry and running northeast through Washington village to meet the North Branch at River Point in West Warwick. Where the North Branch is governed by releases from the Scituate Reservoir, the South Branch is a rainfall-driven river, and it behaves accordingly: quicker to rise, quicker to drop, and warmer through the summer. At roughly sixty square miles of drainage at the Washington gauge it is a mid-sized river by Rhode Island standards and a substantial one by the standards of its own branch.
Rhode Island DEM stocks the river with brook, brown and rainbow trout through the spring, and those fish are the backbone of the fishery from opening day into early summer. The deeper mill pools are where they hold longest, and a proportion carry over where shade and depth combine. As the water warms the character shifts and the warmwater species take over, with largemouth and smallmouth bass, chain pickerel, yellow perch and bluegill through the slower reaches. American eel are present throughout and white sucker are common in the gravel runs.
The corridor is a mill corridor, and that shapes the fishing as much as the geology. Stone dams, raceways and granite abutments break the river into a sequence of short pools and drops rather than a continuous run, and most of the productive water sits immediately above or below one of those structures. The gauge at Washington is worth reading before a trip, because the South Branch responds to rain within hours and a modest storm can turn clear wadeable water into something pushy and stained.

Access
Washington - the gauge village and the most direct access to the middle river and the pools around the old mill site.
River Point, West Warwick - the confluence with the North Branch and the downstream limit of the branch.
Coventry - the town covering most of the corridor, with road crossings giving walk-in access to the upper water.
Flat River Reservoir - the impoundment in the headwaters, which moderates flow in the uppermost reaches.
Mill pools - the deep holes above and below the old stone dams, where stocked trout hold longest into summer.
Anthony - a mill village on the lower branch with parking and access to a series of short pools.
Route 117 crossings - the practical road access points for anglers working the river on foot.
Seasons
Spring: the strongest season by far, with heavy stocking, high cold water and trout spread through every pool from opening day.
Summer: warming water pushes the trout into the deepest shaded pools and the warmwater species take over the slower reaches.
Fall: cooling water brings holdover trout back onto the feed, and the river is quiet and pleasant after the summer.
Winter: low and frequently iced in the mill pools, with only the faster water below the dams reliably open on mild days.
