Lake Elwell is an inland freshwater lake in north-central Montana offering flat-water kitesurfing conditions. The lake provides a sheltered environment suitable for learning and practicing technical skills in a controlled setting without ocean swell. However, the spot presents significant limitations: extremely low wind reliability at 12.7% means sessions are infrequent, and average wind speeds of 8 knots fall below the typical 10-12 knot minimum for reliable kitesurfing. Water temperatures averaging 7.3°C require thermal protection year-round. Best conditions occur with easterly or westerly winds providing side-shore access. The lake's enclosed nature eliminates fetch-related hazards but also restricts natural wind acceleration. This spot suits beginners and intermediate riders seeking calm-water practice during favorable wind windows, though frequent travel may be necessary to find rideable conditions. Winter conditions may limit accessibility.
