Saco River

The Saco River begins as a trickle from Saco Lake at Crawford Notch in the White Mountains, winding roughly 136 miles southeast through Bartlett, North Conway, and Conway before crossing into Maine near Fryeburg, and finally emptying into the Atlantic at Saco Bay near Biddeford and Saco, Maine. It's a classic freestone river — meaning its flow is fed by rain and snowmelt rather than a dam-controlled source — and that gives it a personality that shifts dramatically with the seasons. In early spring, the Saco runs high, fast, and cloudy with runoff from Mount Washington and the surrounding peaks; by mid-to-late summer, levels drop and the water turns crystal clear, often shallow enough to wade across in spots, with an average depth of only around 3 feet in popular stretches, though pools can run 6 to 8 feet or more. Access to the river is abundant and varied — from sandy public beaches and swimming holes along Route 16 in North Conway, to canoe and kayak launches like Swan's Falls in Fryeburg, to private waterfront lots and camps that back right up to its banks. For anglers, the upper river near Bartlett holds small native and stocked trout, the middle stretch toward Conway offers larger brown and rainbow trout (some browns reaching up to 6 pounds), and from the Maine border down toward tidal water, smallmouth bass become the main draw, with striped bass taking over near the river's mouth. The best fishing window is generally June through mid-August for trout, while bass fishing peaks in July before slowing as water temperatures fall in September and October. 

The Saco is primarily a paddler's river — canoes, kayaks, and tubes are the norm, with dams below the New Hampshire stretch requiring portage. Swan's Falls in Fryeburg, Maine is the most popular launch on the river, offering hand-carry access, parking, and restrooms for a modest daily fee. Other well-used access points include Canal Bridge Landing and Brownfield downstream in Maine, and on the New Hampshire side, Bartlett's town beach, First Bridge Conservation Area in Conway, and several bridge crossings along Route 302. Motorized boating is limited mostly to the tidal stretch below Biddeford, where public ramps at Camp Ellis and Hills Beach provide trailer access to Saco Bay and popular striped bass fishing grounds. Most Maine access points charge a $10–$25 daily parking/watercraft fee.
