Erie Canal Lock E-26: Restoring a Historic Dam for Continued Service
Along the Erie Canal in Upstate New York, Lock E-26 has served as a critical piece of infrastructure for more than a century. Originally constructed in 1910, the dam and Tainter gate structure had experienced significant deterioration, requiring a comprehensive rehabilitation to restore structural integrity, ensure safe operation, and preserve the site’s historic character.
Working under a long-standing term contract with the New York State Canal Corporation, our team partnered to deliver a multidisciplinary design that balanced modern engineering requirements with the preservation of this historic asset. The project began with detailed site investigations, including surveying, material testing, and geotechnical analysis to understand existing conditions and inform a resilient path forward.
Balancing Structural Performance with Historic Preservation
Design efforts focused on stabilizing and extending the life of the structure while maintaining its original function and appearance. This included the development of soil and rock anchor systems to meet current stability standards and the relocation of the Tainter gate bay to address ongoing scour and foundation concerns along the lock wall.
A new Tainter gate was designed to replicate the historic structure, while the fixed-crest dam, abutments, and associated concrete elements were rehabilitated and resurfaced. Mechanical and electrical systems were upgraded to improve reliability and safety, all while preserving the original operating principles required to meet historic preservation standards.
Guiding Construction Through Analysis and Coordination
To support construction, our team performed detailed hydraulic and dam safety analyses, including upstream and downstream modeling, spillway capacity evaluations, and dam failure assessments. These efforts informed the design and installation of temporary cofferdams and helped guide construction sequencing to reduce risk.
Throughout construction, we provided Engineering During Construction services and developed seasonally adjusted flood-risk guidance to support safe implementation. All work was performed in accordance with NYSDEC dam safety guidelines and State Historic Preservation Office requirements.
Through careful planning, technical rigor, and ongoing coordination, the project restores a vital piece of canal infrastructure while preserving its historic significance—ensuring that Lock E-26 continues to serve the region safely and reliably for years to come.
