According to the Great Sand Dunes National Park and Preserve, Medano Creek is already flowing at 160% of the average. Medano Creek’s flow is now forecast to be over 160% of average in depth and duration for 2019. Due to very high snowpack and cold temperatures, this year’s peak flow is also not expected until early June rather than late May.
If you’re lucky enough to catch the Medano Creek while it’s still flowing, there are numerous outdoor activities for visitors to enjoy including surfing, wading, skimboarding, floating, sand castle building, and sand-sculpting.
