Colorado River Compact

In 1922 Wyoming, Colorado, Nevada, New Mexico, Utah, Arizona, and California signed the Colorado River Compact to help divide water from the Colorado River fairly among the seven states it passes through. Almost immediately, politicians and citizens of all these states began to fight against the approval of the Compact, and it would not be approved until 1944.
