South Hadley Falls is the site of a former waterfall and rapids on the Connecticut River between Holyoke and South Hadley, Massachusetts, where the natural falls now lie largely under the Holyoke Dam. Historically called the Great Falls of South Hadley, the drop in the riverbed was 53 feet, visible until the dam went in.
The falls
What visitors see today is the dam, not the natural falls. The natural portion consisted of minor rapids partly destroyed by the dam, and it is no longer counted as a waterfall. The present dam is a granite structure 1,000 feet wide and 30 feet high, built in 1900. Five rubber bladders along the crest are raised and lowered for hydropower, so the spill ranges from a trickle to a torrent. After heavy rain or during spring snowmelt, water pours over the entire dam, and a steady release at the left end lets fish bypass the turbines.
Getting there
The town's free public parking lot sits near Main and North Main streets in South Hadley. From there the 1-mile Bridge Loop follows Bridge Street (Route 116) onto the Vietnam Veterans Memorial Bridge, with the dam in view upstream; a side trip down the Hadley Falls Station driveway to a fishing platform and the fishway adds 0.6 mile. The Canal Walk, 1.6 miles round trip, goes via Carew Street to Texon Mill Park, where paths lead to the dam, then on to the South Hadley Public Library and the Canal Park overlook.
When to go
Spring brings the highest water over the dam. The Robert E. Barrett Fishway, at 1-3 County Bridge in Holyoke, is open for the 2026 season from May 6 to June 21, Wednesday through Sunday, 9 a.m. to 5 p.m., for guided or self-guided visits to watch migrating fish pass the dam.
On site
At Texon Mill Park, visitors can hear the roar and feel the spray at high water. The library stands directly above the dam, and canal remnants and the site of the old gatehouses can be seen from inside. The river islands below the bridge are roosts for eagles, cormorants and great blue herons during the spring fish run.
History and name
Before the canal, cargo had to be carried 2.5 miles overland around the falls. A canal with an inclined plane opened to commercial traffic in 1795, lifting flatboats past the drop; five locks replaced the plane in 1805, and railroads made the canal uneconomical until it closed in 1862. A wooden dam built in 1848 washed away; a second, from 1849, still stands under water upriver of the present dam.
