Completed in 1945, this structure stands at 25 feet high and stretches 430 feet in length, with a storage capacity of 50 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is equipped with a controlled spillway and a single valve outlet gate.
Despite being classified as having a low hazard potential, Sullivan Lloyd poses a very high risk, rated at level 1. It has not been assessed for its condition and lacks an Emergency Action Plan (EAP). The last inspection was conducted in 2010, with a scheduled frequency of every 5 years. The dam's design includes a stone core and sits on a soil foundation, making it vulnerable to potential failures and emphasizing the importance of regular inspections and maintenance.
Water resource and climate enthusiasts will find Sullivan Lloyd an intriguing case study, highlighting the complexities and risks associated with aging infrastructure. The dam's location in a high-risk area, coupled with its outdated inspection records and lack of an EAP, underscore the urgent need for improved risk management measures and proactive maintenance strategies to ensure public safety and protect the surrounding environment from potential disasters.
