Ice Harbor Lock and Dam is a hydroelectric, concrete gravity run-of-the-river dam in the northwest United States. On the lower Snake River in southeastern Washington, it bridges Walla Walla and Franklin counties. Located eight miles northeast of Burbank and twelve miles east of Pasco, river mile 9.7, the dam's name comes from a tiny bay in the river where boats once tied up to wait for upstream ice-jams to break up.
