February 12, 2020 - Community Update: Dam Demolition to Begin

The Dam at Lock 38 was originally constructed in 1908 and has only undergone one minor rehabilitation since then. Investigations conducted over the winter of 2017 determined that the Dam at Lock 38 required replacing.

Some geotechnical work to provide information for the project took place at this dam and on nearby watercourses in the Fall and Winter of 2016. Geotechnical work provides important information about the composition and integrity of soils and other materials like concrete, which is used to plan the design of projects and structures.

The construction of cofferdams upstream and downstream of the two operable sluices on the dam at Lock 38, allow the creation of a dry workspace within which to demolish and reconstruct a new dam. The new dam must be constructed while still managing water flows through the area. This has been achieved by converting an overflow weir on the dam into an operable sluice, allowing construction to take place in phases, while water management continues. Construction of the brand new dam is expected to complete in spring 2021.
