DURANT, Okla. (KTEN) — The Choctaw Nation Tribal Council unanimously approved a $2.1 billion spending plan for the next fiscal year.

This budget is 15 percent bigger than the previous one.

"The way that we have been able to increase our annual budget is because of our expansion to our gaming facility," said Choctaw Nation Chief Gary Batton. "We have been able to increase our Medicare and Medicaid, and then also this year ARPA dollars has truly helped us offset and save some of our tribal dollars."

The Choctaw Nation estimates a 21 percent increase in revenue this upcoming fiscal year, totaling $2.4 billion. The Hochatown Casino expansion is credited with some of that revenue.

"That facility itself should do probably around $20 million annually a year just itself. That will be a very good impact to the market," said Choctaw Nation Senior Executive Officer of Commerce Janie Dillard.

Chief Batton said the budget took nearly a year to put together. The fiscal year starts on October 1.
