Pueblo Waterworks is the city's premier high-performance river surf park on the Arkansas River, built around a wide, fast, glassy wave that really turns on once flows come up. It's powerful and dynamic rather than forgiving — moderate to higher water is where it shines, rewarding surfers who can handle speed and push turns on a bigger face. Spring runoff through fall keeps it in play for most of the season, giving Pueblo's growing surf scene plenty of time on the water. Add it to the Arkansas River circuit if you want a punchy step up from the mellower local spots.
