Oklahoma, Texas, Arkansas and Louisiana signed the Red River Compact in 1978. The agreement regulates water rights in a large swathe of the four states.
The Tarrant Regional Water District serves parts of 11 counties in Texas, including the city of Ft. Worth. The district wants to tap the Kiamichi River a Red River tributary in Oklahoma and pump the water to Texas for its customers to use. Rudolf John Herrmann and other members of the Oklahoma Water Resources Board said no.
Since Congress approved the Red River Compact in 1980, growth in the Dallas-Ft. Worth metro area has boomed. The population is projected to double by 2060. By then, the Tarrant Regional Water District says its customers’ water demand will far outstrip its supply. Much of the demand comes from Tarrant County, which is home to Ft. Worth.
A key question before the Court is how to interpret compact language governing an area known as “Reach 2, Subbasin 5.” The compact says the four states “shall have equal rights to the use of runoff originating in the subbasin” but Oklahoma and Texas disagree on what that means.
