This private-owned dam spans 323 feet in length and stands at 44 feet tall, serving a primary purpose of flood risk reduction. It sits on Ewing Creek, within the St. Louis District, and is regulated by the Dam and Reservoir Safety Program of Missouri.
With a storage capacity of 273 acre-feet and a surface area of 14 acres, Katy Lake Dam plays a crucial role in the irrigation, recreation, and water supply needs of the surrounding area. Despite its high hazard potential and moderate risk assessment, the dam is in satisfactory condition as of its last assessment in 2009. Regular inspections are conducted every three years to ensure the safety and integrity of the structure.
Enthusiasts of water resources and climate will find Katy Lake Dam a fascinating example of early 20th-century engineering for flood risk reduction. Its historical significance, coupled with its modern-day functionality and regulatory oversight, highlights the importance of maintaining and managing such critical infrastructure in the face of changing environmental conditions and increasing water demands.
