(AP) -- OMAHA, Neb. (AP) -- The U.S. Army Corps of Engineers says it's unlikely to go ahead with plans to release extra water into the Missouri River to help an endangered fish.
The corps has been planning a spring pulse from Gavins Point Dam near Yankton, S.D, for May 1-19.
On Wednesday, the corps said water flowing downstream from the swollen James River and its tributaries is causing high river flows on the lower portions of the Missouri and will likely lead to the cancellation of the pulse.
Two pulses were scheduled for 2010. Similar river conditions forced the cancellation of the March pulse.
The pulses are designed encourage the endangered pallid sturgeon to spawn.
