With more than 325,000 people at risk of losing their primary water source from the century old lock and dam on the Kentucky River, we performed engineering services to reduce the risk of water loss and bring the aging structure up to current criteria. A thorough assessment of existing conditions was performed on the 111 year old structure. This included historical documents, above water conditions, dive inspections, foundation samples, soils, lock walls, main and auxiliary dams, and other ancillary structures. We assessed structural integrity, evaluated design alternatives, performed lock and dam renovation design, and oversaw construction of the improvements.
Our innovative, award winning design using an in-the-wet construction approach, which reduced construction costs, risks, project duration and environmental impacts while ensuring an additional 50 years’ service and preservation of the water supply for seven communities. The renovation design included the construction of new dam immediately upstream of the existing lock and dam structure, a water conveyance system to transfer water from upper to lower pools in times of drought, and scour and slope protection elements.
