Walla Walla River:
The Walla Walla River basin lies between the Snake River basin on the north, the Blue Mountains to the east and south, and the Umatilla River basin on the south and west.
The basin includes parts of Walla Walla and Columbia counties in Washington and part of Umatilla County in Oregon, and covers 1,720 square miles. The basin is approximately 55 miles long by 52 miles wide, with elevations ranging from a high of 6,250 feet to a low of 340 feet. It is located near the boundary between the Blue Mountains (south and southeast) and Columbia River Plateau (north and northwest) physiographic regions. Regional folding around the basin boundary and faulting formed the Walla Walla basin. The major rock underlying the basin is the Miocene Age (15 to 20 million years ago) Columbia River Basalt Group, which consists of a thick sequence of lava flows known to be in excess of 6,000 feet thick near Pasco. Individual flows generally range from approximately 50 to over 150 feet. Unconsolidated gravels and clays overlie the basalt. An extensive deposit of windblown silt (loess soil) called the Palouse Formation covers most of the Walla Walla River basin. This formation eroded and resulted in the gently rolling hills that are typical of the region.
The Walla Walla River itself originates in the northeast corner of Umatilla County in Oregon. It dips south from there and then flows north through Milton-Freewater, crossing the Oregon/Washington border 6 miles north of Milton-Freewater.
The principle tributaries of the Walla Walla include the Touchet River, Mill Creek, and the North and South Forks of the Walla Walla River.
