The final portion of an emergency watershed project — a detention basin at the mouth of Flat Canyon — was completed earlier this fall. The final EWP structure is designed to capture sediment and debris, and prevent flooding. However, since that time some sediment and debris filled some 13 feet of the barrow pit. The result is that debris and water from flash flood events continued to move downstream.
Some 14,000 cubic yards of rocks and boulders were brought into the project to act like filters for debris and sediment. The flood detention structure is designed so that floodwaters will have to pass through two rock structures, which will capture debris.
The series of projects represent a combined investment of $3.2 million, including some $800,000 worth of county contributions. The majority of the projects were funded through the NRCS. Other projects include flood mitigation projects along the Quitchupah Road, Cedar Ridge and Willow Creek. Richfield Reaper
