Miracle Wave

Miracle wave is mellow knee to waist high glass wave that is a miracle when it comes in on the average of every three years but oh so zen-like to surf it. The wave is located 100 yards down from the the outflow of the Chatfield Reservoir into the S. Platte River at the Chatfield State Park adjacent to the dog park.


Miracle needs a flow of at least a thousand cfs (1,000cfs). The wave is shallow and the water, well it usually is baked with dash of E.coli and added in parasites like giardiasis and cryptosporidiosis for good measure, so don't drink the water. Bring a longboard to surf Miracle wave and be prepared to fall flat as possible due to the rocks right behind and all along the wave. Last time the wave came in it was 2019 and 2016 before that. Unfortunately with the completion of the expansion of the Chatfield Reservoir in 2020 that increased the ability to hold more water, it will take an epic water event (aka crazy amount of rain) or an incredible snow season for the water managers to open up the gates to dump another 1,000cfs or more of water, but never say never.... The first stream gauge to watch for Miracle and many of the other S. Platte surfable waves is the South Platte River Below Chatfield Reservoir (PLACHACO) but the Union gauge is also a good indicator but it is hours down river from Miracle and you will be missing the wave when it comes in and the flow lasts a day or two if not only a few hours... Find more detailed info at http://endlesswaves.net/waves/miracle-wave/ but stick to checking the surf reports at Snoflo for the inside info of when Miracle is surfable.

Ethan getting the start of the wave showing up at Miracle in June 2019 and he had it dialed in for sure.... Notice how wide and glassy this urban river wave is in metro Denver.
