Five Ditches Project
Goal: Replace the headgate with automated water control gates, stabilize surrounding streambanks, and restore riparian habitat
Status: Completed Spring 2019.

Construction
The Consolidated Ditch, Pace Ditch, San Luis Valley Canal, Centennial Ditch, and Rio Grande #2 Ditch divert water off the Rio Grande to irrigate a combined 35,906 acres of agricultural land. Each ditch is facing issues of aging and inefficient diversion infrastructure, and the river is impacted by nearby channel instability and sedimentation. Additionally, increased water shortages and prolonged drought make accurate water management even more important. Improving the diversion structures and streambanks will improve diversion efficiency and reduce maintenance, enhance the water quality by reducing erosion, improve wildlife habitat, and enhance recreation and safety by ensuring the diversions are passable by fish and boats where appropriate.
