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.

Project Overview
Before: Consolidated Headgate
Construction: Trash Gate
Goal: Replace the diversion and headgates with a radial sluice gate and a fish ladder. The new diversion will maintain existing boat passage. The project will also include stabilization of surrounding streambanks and riparian habitat restoration.
Status: The headgate and trash rack have been installed, and the dam is currently under construction.
