LAS VEGAS (AP) -- Department of the Interior officials say their agency's parks and other projects supported more than 19,000 Nevada jobs last fiscal year.

The federal agency says Monday that the 16 million visitors to national parks, wildlife refuges and other federal lands supported about 10,500 jobs, while energy and mineral development supported close to 6,000 jobs.

The department says Lake Mead National Recreation Area alone supported almost 2,500 jobs. That area sees about 7 million visitors a year.

Interior department officials say their agency's projects and sites made a nearly $2.4 billion impact on the Nevada economy.

Nationwide, they say the economic impact is $385 billion.

The Interior department's responsibilities include managing public lands and natural resources and working with Native American tribes.

State officials will be cracking down on drunk boaters throughout Nevada over the weekend, including at Lake Mead.

Game wardens with the Nevada Department of Wildlife (NDOW) will take part in a nationally coordinated enforcement effort dubbed “Operation Dry Water.” In an attempt to reduce the number of drunken boaters, Operation Dry Water is an effort to coordinate increased patrols, investigations, and operating under the influence check points.

Events will take place at including Lakes Lahontan, Mead, Tahoe, Mohave, Topaz, and South Fork Reservoir. 

“We want people to go boating and have fun, but drunken boaters cause accidents and fatalities," said Capt. David Pfiffner, Nevada’s Boating Law Administrator. "Of our fatal accidents, almost half in an average year are alcohol related. Too many people are getting hurt because of a senseless, selfish act of some people.”
