Others spent the night at the new Hardin detention center. That was only temporary, however, and a shelter in Hardin was reopened at the Buddy Roger’s House of Hope on Monday.

Black Eagle and David Yarlott flew the reservation on Sunday in a helicopter contracted out of Lewistown. They noted several isolated homes where people were stranded and reported them to incident command in Crow Agency. The helicopter will be used for the duration for medical evacuations and to deliver emergency supplies.

Supplies and a Big Horn County Health Department nurse were ferried to water-bound Lodge Grass, part of the way by boat.

Vehicles took the supplies as far as possible toward the flooded area of Interstate 90 where a boat carried them to dry pavement on the other side. From there, they were driven to Lodge Grass, where another boat took them to dry areas of the town. A shelter has been set up at Lodge Grass High, the highest point in town.

Lodge Grass is without electricity or telephone service, but at last report had clean water.

Black Eagle said there is no way yet to tell how many homes were flooded, bridges damaged or roads washed away. An on-the-ground assessment will be made as soon as waters recede, he said.
