The full flood-control capacity of the Missouri River Reservoir system upstream from Omaha is available for the spring runoff season.

All 2015 stored floodwaters have been evacuated from the reservoir system, according to the Army Corps of Engineers' river management office in Omaha.

During the winter, the corps will closely monitor conditions throughout the basin and make reservoir regulation adjustments to lessen the impact of river ice formation, said Jody Farhat, chief of the water management division.

As of Feb. 1, mountain snowpack was 92 percent of average in the region above Fort Peck Dam in Montana and 72 percent of average in the reach from Fort Peck to Garrison Dam in North Dakota. Normally, 64 percent of the total mountain snowpack accumulation has occurred by Feb. 1. Mountain snowpack will continue to accumulate over the next few months and normally peaks in mid-April.

January runoff above Sioux City, Iowa, was 114 percent of average. Based on the current soil moisture and mountain and plains snowpack conditions, runoff in the Missouri River Basin above Sioux City is forecast to be 92 percent of average this year.
