HYRUM, Utah — A federal Bureau of Reclamation official says technicians are drilling for more samples in a study of how the Hyrum Reservoir dam would hold up in an earthquake.

Project engineer Mike Talbot told the Herald Journal in Logan that workers conducted similar geotechnical exploration studies at the dam in June, but needed to returned for more testing.

Crews plan to finish one bore hole begun at that time, and drill another.

The dam was built in 1934 and 1935 to provide flood control and irrigation water storage.

Talbot said previous samples didn't immediately show any cause for concern.

The work started last Wednesday is scheduled to last into next week.
