U.S. Army Corps of Engineers officials say they've found no indication of major problems with Gavins Point Dam related to the 2011 flood.
Discharges at the dam were increased Tuesday during a spillway flow test to assess the spillway's current condition.
The corps is continuing to investigate potential flood damage to the structure. Sonar tests last year detected anomalies below the spillway.
The corps' John Bertino, chief of the engineering division for the Omaha District, says Gavins Point is a unique spillway that is submerged most of the time, so it's more difficult to evaluate than upriver structures.
