HELENA - Water-damaged Big Horn County is ordering 50,000 sandbags in preparation for more flooding next week.
Officials on the Crow Indian Reservation say they will use about 10,000 of those bags to protect septic operations and other important areas.
Mild weather is allowing tribal officials and counties across Montana to make repairs and prepare for next week, when runoff from the melting snow pack is expected to cause more flooding.
With the receding waters, displaced reservation residents are being relocated from Billings to a new shelter on Crow Agency.
The reservation's septic facility is not operating and the water system is damaged. Residents are advised to boil tap water before drinking.
Federal emergency teams will begin assessing the flood damage in Montana on Thursday to see if federal aid is required.
