Department of Agriculture's Bureau of Biological Survey. This Federal-owned structure serves as a Fish and Wildlife Pond on Lamesteer Creek, with a primary purpose of supporting the local ecosystem. The dam stands at a height of 22 feet, with a hydraulic height matching that figure. Its design involves an Earth core supported by Stone foundations, spanning a length of 1830 feet and offering a maximum storage capacity of 1470 acre-feet.
Despite its low hazard potential, Lamesteer Dam received an Unsatisfactory condition assessment during its last inspection in September 2020. The risk assessment for the dam is classified as Moderate (3), highlighting the need for continued monitoring and potential risk management measures. With no state regulation or jurisdiction, the Federal agency DOI FWS oversees the operation and maintenance of this vital water resource. As water resource and climate enthusiasts, the unique characteristics and challenges of Lamesteer Dam present an intriguing case study in sustainable water management and infrastructure maintenance.
