Wind erosion contributes to the formation of lake basins on the North American plains primarily through a process known as deflation. In this process, wind removes loose, dry, and uncemented sediments from flat areas, creating depressions called deflation hollows or blowouts.1

On the plains east of the Rocky Mountains, including regions extending into Texas, many lake basins are believed to have originated, at least in part, from this wind-driven erosion. These basins form as the wind excavates material until the surface reaches the water table, at which point further erosion is typically inhibited unless the water table itself is lowered by evaporation. Additionally, wind can influence lake formation through the construction of dunes; for example, Moses Lake in Washington was created when windblown sand acted as a dam to obstruct a basin.21
