In pioneer days, boats needing to pass the bedeviling rapids near the town of Whiskey Flats had to portage around them. The locks that gave the town its new name were completed in 1896, allowing waterborne passage for the first time. In 1938 they were submerged beneath the new Lake Bonneville when the Bonneville Lock and Dam became one of the most massive Corps of Engineers projects to come out of the New Deal. The town of Cascade Locks hung on to its name, though. A historic stern-wheeler still leads excursions from the town's port district, and the region's Native American tribes still practice traditional dip-net fishing near the current locks.
