Through Saturday, 13.39 inches of rain soaked Sioux Falls. That's more than half the yearly average precipitation of 26.38 inches, and far above the previous wettest month on record (9.42 inches in May 1898). The rains have left some fields in southeastern South Dakota submerged.
Anthony Bly is soils field specialist with South Dakota State University Extension's Sioux Falls Regional Center. He says how long crops survive depends on how long the water sticks around.
