Lacamas & Round Lakes Upper Dam, located in Camas, Washington, was completed in 1936 and serves as a crucial water supply source for the area. The dam, with a hydraulic height of 28 feet, holds a storage capacity of 6800 acre-feet and covers a surface area of 350 acres. It is primarily designed as a buttress dam, supported by a multi-arch core type and built on a soil foundation.
Managed by the Washington Department of Ecology, the dam is regulated and inspected regularly to ensure its safety and efficiency. With a high hazard potential due to its location on Lacamas Creek, the dam is assessed to be in satisfactory condition as of April 2018. Emergency action plans are in place, though details of their last revision and effectiveness meeting guidelines are not specified in available data.
The surrounding area offers recreational opportunities, in addition to its water supply function. The dam, situated in a scenic location, plays a vital role in maintaining water levels for both practical and leisure purposes. Climate and water resource enthusiasts will appreciate the significance of Lacamas & Round Lakes Upper Dam as a key infrastructure supporting the region's water needs while contributing to environmental conservation efforts.
