River is Raging & the Project Looks Great!

Besides Hot Sulphur Days last weekend, which was a real hoot, the big news in our project area is the raging Colorado River. Flows of up to 2,300 CFS were measured at Windy Gap USGS Gage upstream, and flooding along the river was common. We are happy to report that our water intake area and associated river restoration is handling the flows just fine.



The first photo looking upstream shows river flow over the boulder weir and the intake piping without hardly breaking the surface. The low-profile design is working properly with flood flows passing over the structure without increased shear stress. The riparian restoration work the was done has narrowed the river channel as seen through the shrubs on the second photo and is also holding up quite well. Nick Mezei of the US Army Corps visited the project on June 8 as part of the seasonal monitoring. We will be evaluating the restoration work throughout the year to see if there is scour or sedimentation.
