Firefighters rolled up in front of Harrah’s Lake Tahoe Tuesday morning and caused quite a stir. Traffic was shutdown in one lane. Water was spraying, but no flames were seen.

This is because it was all a test.

Tahoe-Douglas fire crews go out to Harrah’s and Harveys once a year to test the casinos’ fire valves.

“We do this every year. It’s for insurance purposes for the casinos,” explained fire Capt. Terry Hughes. “They have internal fire pumps inside.”

These are the only two Stateline casinos the fire district does the test for.
