About this lake
Diaz Lake is an 80-acre Inyo County lake 3 miles south of Lone Pine on Highway 395.
On the water
The county lists swimming and waterskiing among the lake's uses and has a launch ramp. Motorized boats pay $10 a day and may run from 8 a.m. to 2:30 p.m. The 2026 motorized season opened May 15 and closes November 1, 2026. Kayaks, canoes and other non-motorized boats are allowed year-round. Inyo County requires watercraft to be inspected for invasive mussels before launching.
Camping
The county campground has 100 sites around the lake, with first-come sites and online reservations through ReserveAmerica. Sites are $14 a night plus $5 for each extra vehicle; sites 44 to 46 are group sites for up to 15 people at $35. There are no hookups or showers and only a few water spigots. ATVs aren't allowed in the campground.
Fishing
Shore fishing is open year-round. An ADA fishing deck sits near the launch ramp.
