DONNER SUMMIT, Calif. — This weekend, the Cisco Grove Campground will see thousands of people migrate into the 300-acre sprawl of land located high up in the Sierra Nevada.

They’ll dance, they’ll sing, they’ll celebrate — basking in soul-filling scenery and sounds.

Moreover, the people will be rallying together for an important cause: raising awareness for protecting and preserving the waterways of Truckee-Tahoe and — on a larger scale — all across the globe.

Starting Thursday, the sixth annual Guitarfish Music Festival will reel in the music-loving, environmentally conscious crowds for the four-day event at Cisco Grove Campground, located roughly a half hour west of Truckee, just off Interstate 80.

The four-stage festival will feature an eclectic mix of acclaimed acts, epitomized by the batch of headliners: jam band ALO, jazz quintet the Greyboy Allstars, seven-piece rock/soul band Sister Sparrow and the Dirty Birds, and funk outfit Orgone.

In all, 30 bands will plug in and play at Donner Summit this weekend.

Festival organizers are expecting more than 2,000 people to partake in this year’s event, said Marshall Lamm, a festival spokesman. Six years ago at the inaugural Guitarfish, the number of attendees was roughly 1,000, he added.

“In (Lake) Tahoe and Northern California, there’s such a huge interest and motivation from people to do more for the environment,” Lamm said. “Guitarfish really puts it out there and the festival is a forward-thinking and progressive when it comes to protecting and preserving our waterways — Lake Tahoe, all of the different fisheries — and just how our day to day lives can be affected by what we do.”

With that, the marine-themed festival will also feature activities aimed to educate and give guidance on topics like overfishing, pollution of the ocean and conserving fresh watersheds, rivers and streams.

Other attractions at the festival include yoga, discussions with eco experts, food and drink vendors, costume themed contests, late night shows, interactive art installations, and an array of outdoor activities.

“It will be very family orientated — people are taken care of, that’s a big focus of the festival,” said Lamm, adding that the festival’s Sierra Nevada backdrop creates a special atmosphere. “It encompasses what Guitarfish is all about. You’re out in the woods camping and you’re one with nature; you’re together with everyone who’s out there. It creates a very unique experience.”
