About the water
A reservoir with roughly 53 miles of shoreline used for wakeboarding, water skiing, and tubing, with boat ramps and a marina at Keyhole State Park. It sits near Devils Tower in the northeast corner of the state.
Wyoming wake-sport rules
Wyoming has no statewide wakesurfing-specific regulation. A statewide requirement mandates that anyone wake surfing (or riding a PWC) wear a life jacket, and many smaller waters carry boating/motor restrictions, but there are no wake-surf-specific distance, depth, or lake-size thresholds.
This rating classifies measured depth and surface area against published wake-sport guidance. It is not a safety clearance and not permission to ride: local no-wake zones, hours, and horsepower limits are set by the county, lake district, or land manager, and they take precedence. Lake measurements from Wyoming State Parks.

This is a read of the water's dimensions, not legal permission — check the Wyoming rules and the local authority for this lake before you launch.
No maximum-depth measurement is on record for Keyhole Reservoir in the state agency data we use, so its depth factor is unrated. We do not estimate depth.
Keyhole Reservoir carries a LakeQuality water-quality grade of B, computed from EPA and state monitoring data — Secchi clarity, total phosphorus, and chlorophyll-a. That is a separate question from wakesurf suitability: a lake can be excellent to ride and mediocre to swim in, or the reverse. See the full lake page for the grade breakdown.
Wyoming has no statewide wakesurfing-specific regulation. A statewide requirement mandates that anyone wake surfing (or riding a PWC) wear a life jacket, and many smaller waters carry boating/motor restrictions, but there are no wake-surf-specific distance, depth, or lake-size thresholds. Individual lakes often add stricter local limits on top of the statewide rule — no-wake zones, operating hours, and horsepower caps are all common — so confirm with the local authority for Keyhole Reservoir.
