Swimming & Beach

Yes, you can swim at Jordanelle Reservoir. The public beach is in the Hailstone day-use area, off US-40, with 38 reservable cabanas, three group pavilions, a playground and a volleyball court. Swimming is not allowed inside the marina, from the docks, or past the buoys near the dam. Before you go, check the algae status Utah's Department of Environmental Quality posts for the reservoir, which the park page links to. Day-use is $20 per vehicle from May through October.

The Hailstone Beach

At Hailstone, Utah State Parks lists beach access, a playground between the Beach House and the Beach Pavilion, and a volleyball court beside the Sand Pavilion. Paddleboard lockers are rented nearby, and the Hailstone Marina rents kayaks and paddleboards if you want to get out past the beach (Boat Rentals).

Utah State Parks' Jordanelle pages don't mention lifeguards, so watch children closely and use life jackets.

Cabanas

Hailstone has 38 day-use cabanas you can reserve. Each has one covered picnic table, a pedestal grill and one reserved parking spot, for $50 a day; that covers entry for one vehicle, and everyone else in your group pays the day-use fee. Ross Creek has 24 more cabanas, all first come, first served: 12 on sand and 12 on concrete pads with tables (Ross Creek). Cabanas are closed from November through April.

Group Pavilions

Three pavilions at Hailstone hold up to 75 people each and cost $250, which covers entry for five vehicles. They can be reserved up to 11 months ahead.

• Sand Pavilion: right on the public beach next to the volleyball court. Half concrete, half sand, with a block barbecue pit, a pedestal grill, nine large picnic tables and five parking stalls. ADA accessible.
• Beach Pavilion: beach and playground access, nine picnic tables, a fire pit, a large pedestal grill, lights and five parking stalls.
• Cove Pavilion: nine picnic tables, a large pedestal grill and five parking stalls.

None of the pavilions has motorized boat access.

Is It Safe to Swim Right Now?

Utah State Parks links the reservoir's current algae status to Utah DEQ's Jordanelle Reservoir page, right on the park page, and posts the current water temperature there too. Check both on the day you go. Utah State Parks' water safety page has general tips for open-water swimming.
