Montrose Water Sports Park on the Uncompahgre River in Montrose, Colorado runs on irrigation-season flows, which makes it one of the most dependable river waves in the state through spring and summer. The first and second drops are where the high-performance surfing happens, throwing steep, punchy faces for experienced riders. Drop four is the mellower option, a solid entry point if you're still building your river surfing legs. Flows shift the whole park's character, so expect faster, more dynamic wave shapes whenever the irrigation releases run high.
