Palouse River at Lyons Ferry State Park confluence with Lower Snake River below Little Goose Dam near Perry, WA. The Palouse River is a tributary of the Snake River located in the U.S. states of Washington and Idaho. It flows for 167 miles (269 km) southwestwards, primarily through the Palouse region of southeastern Washington. Its canyon was carved out by a fork in the catastrophic Missoula Floods of the previous ice age, which spilled over the northern Columbia Plateau and flowed into the Snake River, eroding the river's present course in a few thousand years.
