SIOUX FALLS, S.D. (AP) - Runoff from rain was enough to support downstream barge traffic in April, allowing the Army Corps of Engineers to save water in the six reservoirs on the Missouri River.

Fort Peck, Oahe and Fort Randall reservoirs gained from 1.2 to 1.9 feet of water in April. The other three reservoirs _ Garrison, Big Bend and Gavins Point _ lost from 0.1 to 0.3 feet, the corps said.

"The rain pushed the Missouri River well above full service navigation flows from Rulo, Neb., to the mouth, allowing us to maintain releases from the reservoir system at extraordinarily low levels for this time of the year," said Larry Cieslik, chief of the water management office at the corps' Omaha, Neb., office.

The steady to rising reservoir levels should provide good spawning conditions for fish, he said.

Runoff above Sioux City, Iowa in April was 72 percent of normal. Runoff for the year is expected to be 20.3 million acre feet (MAF), 81 percent of normal. The mountain snowpack peaked in late April at 77 to 81 percent of normal, the corps said.
