Misselbeck, also known as Rainbow Lake, is a public utility dam located in Shasta, California. Built in 1920, this earth dam stands at 96 feet tall and stretches 470 feet in length, with a storage capacity of 3,600 acre-feet. The dam serves multiple purposes, including flood risk reduction, irrigation, and water supply for the surrounding area along Nfk Cottonwood Cr.

Despite its significant contribution to water resource management in the region, Misselbeck poses a high hazard potential due to its poor condition assessment. The dam has been flagged for regular inspections and enforcement by the California Department of Water Resources (DWR) and Safety of Dams agency. It is crucial for water resource and climate enthusiasts to monitor the maintenance and risk management measures for Misselbeck to ensure the safety of downstream communities in the event of an emergency.

Given its historical significance and vital role in water supply infrastructure, Misselbeck underscores the importance of proactive monitoring and maintenance of aging dams. As a key player in flood risk reduction and water supply management, the dam's condition assessment, emergency action plan preparation, and risk management measures must be regularly updated to mitigate potential hazards and safeguard the surrounding environment and communities. Continued oversight and investment in the upkeep of dams like Misselbeck are essential for sustainable water resource management in the face of changing climate conditions.
