About This Route
Gunlock Reservoir, 45 minutes northwest of Zion via I-15, features slot canyons and waterfalls ideal for pre-surf swims, but wakesurfing thrives in the 1,400-acre main basin. Access via the southern ramp; cliff jumping zones separate from surf areas. Low water exposes lava rocks; verify levels at Utah State Parks site. Popular for Liquid Force board demos, it's less crowded midweek.
Safety Considerations
Flash floods from upstream washes close ramps; monitor NOAA gauges. Steep shorebreaks eject riders; enter from boats only. Cyanobacteria blooms toxic; avoid if green scum visible, per DEQ advisories. Jet ski traffic high; yield to larger vessels. Core strength vital; fatigue leads to ejections at 10-11 mph boat speeds. Helmets recommended for tricks per Red Bull safety standards. Sunscreen into water; coral-like algae cuts infect fast.
