Haldi and Left Hand Valley Diversion Projects
Prioritized through the Left Hand Creek Feasibility Study, the Haldi and Left Hand Valley Diversions are key points of diversion in the Left Hand Creek Ditch System. Through collaboration with water managers and ecologists, we developed broadly supported multi-benefit conceptual designs that offer opportunities for enhancing operations and maintenance at these structures while benefitting fish habitat and connectivity. Today, we are working with project partners to further develop designs towards implementation.
