Aaron Payment, the chairman of the Sault Tribe of Chippewa Indians in Michigan, said his tribe had already shut down its H.I.V. prevention program and furloughed employees for its Head Start program for a month because of sequestration.
Now, with nearly $1 million in federal money lost since the shutdown, the tribe is scrambling to shift casino revenue from other programs to keep its government afloat.
“We’re in turmoil right now,” Mr. Payment said. “The impact here is going to be felt by the people who need the services the most.”
Kevin Washburn, assistant secretary for Indian affairs, said the shutdown could have long-term effects on tribes and tribal members. Financial deals and economic programs have been suspended. Environmental reviews of tribal projects will be delayed. And the impact on the thousands of Bureau of Indian Affairs employees who have been furloughed is compounded because many support poor relatives, he said.
