What happened

The episode as NWS BOI wrote it up.

Due to extensive rainfall and warm temperatures, flooding took place at several locations. Damage occured on the Middle Fork of the Weiser river where sandbags were needed to protect a house. The Payette river at Emmett rose above flood stage causing a levee near Fruitland to fail. A section of State Route 52 was flooded three miles east of New Plymouth and several homes near Black's Bridge were flooded. Five homes were evacuated. In Southeast Idaho, Henry's Fork river closed the Parker-Salem highway due to high water as well as causing low-land flooding west of Rexburg. The Portneuf River at Pocatello rose above flood stage causing low land flooding along Marsh Creek and between Inkom and Pocatello.
