|Description=The Colorado River Compact aims to provide for equitable division of Colorado River Waters between the seven basin states. The basin states are divided into Upper Basin States: Colorado, New Mexico, Utah and Wyoming; and Lower Basin States: Arizona, California and Nevada. The agreement allocates 7,500,000 acre-feet per year to both the Upper and Lower Basin states <ref name=“USBR 1922”> Colorado River Compact.

In addition, the Lower Basin states were granted to the right to increase its use by up to 1,000,000 acre-feet per year. Water allocated to Mexico is to be supplied from the surplus and in the event that the surplus is not sufficient, the Upper and Lower Basin states will equally decrease their consumption to make up the deficiency. Allocation quantities were based on 22 year record of river flows which suggested that a flow of 16,500,000 was a conservative estimate <ref name=“Morris 1997”> Morris, R., Devitt, D. A., Crites, Z.
