Weeks Falls is a waterfall on the South Fork Snoqualmie River near North Bend, Washington, with easy public access from Interstate 90 and Olallie State Park. A gravel parking lot, paved accessible overlook, and nearby quarter-mile accessible interpretive trail make it both a roadside stop and a short walking destination. The site also includes a small area around a run-of-the-river hydroelectric facility. Owned by Eagle Creek Renewable Energy and operated by PIC Group, Inc., the plant diverts water from above the falls through an underground channel to a single generating unit with a 4.3 megawatt capacity, producing 13.1 gigawatt-hours of electricity annually as of the end of 2024.
