Tim McGraw, Lady Antebellum and Jake Owen have been announced as headliners for the third annual Watershed Music Festival, held Aug. 1-3 in George, Wash.

They will be joined by some of country music's biggest stars for the three-day event, including Kip Moore, the Eli Young Band, Joe Diffie, Randy Houser, Justin Moore, Cassadee Pope, Eli Young Band, Chase Rice and Dallas Smith. More artists are expected to be announced at a later date.

“After I performed there last year I knew this was the kind of festival I would want to come back and play as many times as I can," Moore explains. "It's such an iconic and beautiful place to play and adds to what is already a great vibe. And there are tons of hardcore fans, which just amps it up to an insane level.”

"We've been lucky that this crazy idea has turned into a monster country festival now celebrating its third year," Brian O'Connell, creator of Watershed Music Festival and Live Nation President of Country Touring, says. "Each time we try and top ourselves and do better than the previous year, and 2014 is no exception. We're looking forward to another fun and crazy weekend with top notch talent."

The Watershed Music Festival is held at the famous Gorge Amphitheatre, which overlooks the picturesque Columbia River. Camping is also available during the festival.

Three-day festival passes and camping sites will go on sale on Thursday, March 13, at this link.
