SIOUX FALLS, S.D. — The Corps of Engineers plans to send more water down the Missouri River to help the endangered pallid sturgeon.
The agency said a small pulse will start Saturday, increase for two days, then decrease starting Monday and return to minimum navigation flows by late next week.
The spring pulses are meant to replicate what once was a natural occurrence when melting snow caused a heavy flow of water downstream.
The pulse will coincide with the annual increase in releases from Gavins Point Dam near Yankton, S.D., to provide more water for commercial navigation and other downstream uses from Sioux City, Iowa, to the Mississippi River.
River levels are expected to rise 1.5 feet at Sioux City and Omaha, Neb., and less than half a foot at Hermann.
