Natural Resources Division July 21, 2020 ICWP Interstate Water Management Committee 11 , Red River Compact Article VII of the Red River Compact contains provisions for apportionment of water in Reach IV.Sections 7.01 - 7.03, as contained in Article VII, are included below. Reach IV of the Red River is divided into topographic subbasins, and the water therein allocated as follows: Section 7.01 Subbasin I - Intrastate streams - Arkansas. This subbasin includes those streams and their tributaries above last downstream major dam sites originating in Arkansas and crossing the Arkansas-Louisiana state boundary before flowing into the Red River in Louisiana. Those major last downstream dam sites are as follows: Lake Catherine (Ouachita River), DeGray Lake (Caddo River), Lake Greeson (Little Missouri River), and Lake Winona (Saline River). b) Arkansas is apportioned the waters of this subbasin and shall have unrestricted use thereof.
