The beauty queen of Utah’s reservoirs and dams is the Upper Stillwater in Duchesne County. Throughout the spring—especially in years with high snow or fast-melting conditions—the dam fills with water and eventually spills over the steep stepped spillway.
When it spills, the water falls to the tune of 600 feet wide and 200 feet tall. It is as deep as (or maybe even a little deeper than) Niagara Falls! It’s such a beautiful sight. If you’re able to make it during the few days this happens, we highly recommend it.
At the time of writing this blog post, the Upper Stillwater is 39% full. Two days ago, it was 29% full. At this rate, we’re anticipating it to spill sometime in mid-June. You can monitor the reservoir levels anytime by visiting our Data Page. Fun fact: this year, we anticipate all of our reservoirs will fill up, with the exception of Strawberry, because of its size.
Have you ever had the chance to see the Upper Stillwater spill? If so, we’d love to hear about it and see any photos you have! Share them with us on our social media channels or tag #CUWCD when you post them so we can find them. This year is the perfect year to either see it again or experience this beautiful scene for the very first time!
