Flood stage at Fort Pierre is 21 feet, and the river rose to around 25 feet on the 21st. The Bad River went below flood stage during the afternoon of the 22nd. Lowlands near the river were flooded along with some county roads with some of the roads damaged. Late in the evening of the 20th, the trailer court on the southern edge of Fort Pierre was evacuated where they did some sandbagging. Also, on the west side of Fort Pierre, some roads were flooded.
