The U.S. Bureau of Reclamation says it will continue to release water from a southwest Nebraska reservoir to relieve stress on a damaged dam. The bureau says it found cracks in the Red Willow Dam’s embankment. Engineers have been examining the structure since a sinkhole was discovered in October. Red Willow Dam is 126 feet tall and it forms a reservoir of 85,070 acre-feet. It’s located about 11 miles north of McCook.
