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 faced issues of aging and inefficient diversion infrastructure, and the river was 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 has improved diversion efficiency and reduced maintenance, enhanced the water quality by reducing erosion, improved wildlife habitat, and enhanced recreation and safety by ensuring the diversions are passable by fish and boats where appropriate.
