Lake Hattie is an inland reservoir in Wyoming offering flat-water kitesurfing conditions suitable for beginners and progression riders. The lake's north-south orientation with developed eastern shores provides relatively protected water with minimal wave action. The spot features shallow areas near the northern embankment and agricultural lands to the east, limiting wave development even in stronger winds. Wind patterns are highly seasonal and unreliable (13.4% reliability), with average conditions of 8.4 knots typically insufficient for kitesurfing. Best conditions occur with easterly or westerly winds that run parallel to the main water body, providing side-shore access from the eastern agricultural areas or western undeveloped shoreline. The lake's shallow nature and infrastructure (dam, power lines, access roads) require careful navigation. Water temperatures remain cold year-round (averaging 6.4°C), necessitating appropriate thermal protection. This spot suits beginner riders seeking flat-water progression in calm conditions but requires patience due to inconsistent wind availability and generally light average wind speeds.
