During the Great Depression, in portions of the North American Great Plains there was a years-long drought, leading to soil erosion and dust storms usually referred to as the Dust Bowl. Crops failed, forcing many farmers to leave in search of work elsewhere, notably California. Many of the displaced were from Oklahoma, where 15 % of the state's population left it, and became known as Okies.
In South Dakota on November 11, 1933 a very strong dust storm stripped topsoil from desiccated farmlands in just one of a series of disastrous dust storms that year. Then on May 11, 1934 a strong two-day dust storm removed massive amounts of Great Plains topsoil in one of the worst such storms of the Dust Bowl.

OKI has held four public open houses throughout the region to kickoff the 2030 Regional Transportation Plan Update.
OKI's experience with STEAM to date has largely been experimental.
OKI has invested the staff time necessary to master the underlying economic concepts, extract and format the travel demand outputs, and to master the STEAM software itself.
