HOLDREGE, Neb. (AP) — Plenty of water is headed for the Platte River in Nebraska, but officials don’t know yet how much and when it will arrive.

Engineer Cory Steinke told the Central Nebraska Public Power and Irrigation District board members Monday in Holdrege that the water will come from the basin’s rain runoff, nearly full Wyoming reservoirs upstream of Lake McConaughy (muh-KAHN’-uh-hay) on the North Platte River and deeper-than-average snowpacks in the Rocky Mountains of Colorado and Wyoming.

Steinke says there isn’t much room in the upstream reservoirs for a higher-than-normal snowpacks. He says releases from the Glendo Reservoir upstream from Lake McConaughy have been increased.

On Monday Lake McConaughy was holding about 1.5 million acre-feet of water — around 85 percent of maximum.
