Mill Creek near Pagosa Springs, CO – Levine

Channel degradation and bank erosion from over-grazing and poor management of irrigation water had led to poor water quality conditions and a lack of riparian vegetation. Riverbend Engineering’s design provided a “two-tiered” channel and floodplain system, where typical irrigation driven low flows would sustain a smaller channel and floodplain inset into a larger channel and floodplain system. Riverbend’s design solution included narrowing and re- shaping of the active channel, grading of point bars and low floodplain areas, preventing bank erosion with rock piles and willow transplants. Grazing limitations were placed on the riparian zone, and new irrigation ditches were cut to better manage their water resources.
