Built in 1967, this earth dam on Icy Creek serves primarily for irrigation purposes, with additional recreational benefits. The dam has a hydraulic height of 15 feet and a structural height of 12 feet, with a length of 385 feet and a storage capacity of 96 acre-feet.
Despite its critical role in water resource management, Lake Kittyprince Dam has a high hazard potential and a poor condition assessment as of the last inspection in June 2015. The Washington Department of Ecology regulates and inspects the dam, ensuring its continued safety and functionality. However, there are no spillways or outlet gates specified for managing excess water flow, posing a potential risk in the event of heavy rainfall or flooding.
The dam's location in a densely populated area underscores the importance of regular monitoring and maintenance to prevent any potential emergencies. With its historical significance and ecological impact on the surrounding area, Lake Kittyprince Dam serves as a vital infrastructure for water supply and recreational activities, highlighting the intersection of water resources management and climate resilience in the Pacific Northwest.
