Photos Show Historic Flooding In 1962 After Construction Of Gavins Point

NEBRASKA CITY – The family of Robert Aksamit, a former Nebraska City grain dealer who provided grain prices for years with Bartlett Grain, provided US Army Corps of Engineer photographs of flooding and construction of the Gavins Point.

Gavins Point is the farthest downstream of the corps’ main stem dams, including Fort Peck, Garrison, Oahe, Big Bend and Fort Randall.

At a recent corps meeting in Nebraska City is was described as a structure used to regulate water flows, rather than storage of large amounts of water.

A photo shows construction on May 16, 1955.

It shows the spillway gate structure in place. Workers are erecting a service bridge on top of the spillway.

A huge, reinforced concrete structure, the Gavins Point spillway was said to have a discharge capacity of 571,000 cubic feet per second, a paved length of 526 feet and is 664 feet long at its crest.

“Working as a safety valve, this structure will prevent floods from overtopping the embankment.”

Fourteen tainter gates, each 40 feet wide and 30 feet high, will control the flows.

Operating at its capacity, the big concrete chute is capable of discharging more than 250 million gallons of water per minutes.

The photos also include flooding on the Elkhorn River, taken March 28, 1962. A photo taken on Highway 275 near Scriber shows damage to the highway by a Elkhorn River flood.
