The federal government is going to check the integrity of the Blue Mesa Reservoir dam which is pushing 50 years old. Drill samples will be taken beginning Wenesday with up to five minute traffic delays on Highway 92.

The Bureau of Reclamation say the drill samples are "pretty routine kinds of tests" and that they are just checking the dam to make sure "everything is looking good".

Core samples will be taken as well as dropping instruments in one of the three holes to monitor the dam.
