Jez Grand Coulee

Jez Grand Coulee (ang. Grand Coulee Dam) je velik gravitacijski jez na reki Kolumbija. Nahaja se v zvezni državi Washington, ZDA. Uporablja se za generiranje elektrike in namakanje. Gradnja se je začela leta 1933, odprli so ga leta 1942. Leta 1974 so dogradili še tretjo elektrarno in tako povečali kapaciteto. Grand Coulee je s 6,8 GW največja elektrarna v ZDA.
