Summary

Description

Upload is a series of profiles for the Lake Lewis level reached for various flood sizes. w:Lake Lewis was a temporary lake in the Pacific Northwest region of North America, largely formed by the Missoula Floods in about the 14th millennium B.C.

Lake Lewis was formed when the restricted flow of waters[1] from periodic cataclysmic floods from w:Glacial Lake Missoula, pluvial Lake Bonneville, and perhaps from subglacial outbursts, backed up through the constriction formed by the Wallula Gap in the Horse Heaven Hills (southern Washington). Water also backed up further downstream on the Columbia River between Washington and Oregon, delaying the drainage of Lake Lewis. The water remained for a period of weeks before the flood waters drained through Wallula Gap, just southeast of the Tri-Cities area. Lake Lewis reached an elevation of about Template:Ft to m above sea level (today's sea level) before subsiding.
