What the National Weather Service wrote

Snow melt began in earnest with warmer temperatures combined with periods of heavy rain in the latter half of March. This caused extensive sheet flooding in Clark County to the extent that the governor declared it a state of Idaho disaster area. Several county roads received extensive damage and were washed away. 1 home in the Medicine Lodge area flooded completely along with hay bail damage and crop damage. The Birch Creek Campground also had extensive damage with several campgrounds along the birch Creek washed away. The county placed damage estimates close to 700 thousand dollars.

The wider storm

A return to heavy mountain snows in late February and early March added significantly to the snow pack especially in the Upper Snake River Highlands and snow melt and heavy rains occurred sporadically from the middle of the month onward. The worst of the flooding occurred in Clark and Madison which were both declared state disaster areas by the end of the month. Low elevations in the central mountains also began to experience with extensive damage also occurring in Blaine County.

Began near Kilgore (44.5023, -112.0234).
