Ice Harbor Lock and Dam is a hydroelectric, concrete gravity run-of-the-river dam on the Snake River in Walla Walla and Franklin counties in the U.S. state of Washington. The dam is located 8 miles (13 km) northeast of the town of Burbank and 12 miles (20 km) east of Pasco, river mile 9.2. Its name comes from a tiny bay in the river where boats once tied up to wait for upstream ice-jams to break up.
