In nature, water always wins. We’ve tackled that challenge on thousands of bridges, dams, channel improvements, roadways, and floodplains. And we lead the way on river hydraulics.

Developed by Xcel Energy and Ayres engineers, the award-winning hinged floating bulkhead has become a valuable tool, particularly in dewatering tainter gates for rehabilitation and testing. The system has been used at projects across the nation to safely, efficiently, and economically dewater spillway gates and powerhouse intakes.
