Built in 1950, this earth dam stands at 15 feet in height and stretches 400 feet in length, with a storage capacity of 80 acre-feet. Despite being rated as having a low hazard potential, the risk assessment for Gill indicates a very high risk level, emphasizing the importance of ongoing monitoring and maintenance.
Managed by the Oklahoma Water Resources Board (OWRB), Gill is subject to state regulation, inspection, and enforcement to ensure its structural integrity and operational effectiveness. Although its condition assessment is currently listed as "Not Rated," the dam is equipped with a controlled spillway and a single valve outlet gate for water release. With a history of regular inspections dating back to April 2003, Gill's emergency action plan status and risk management measures are currently unspecified, suggesting room for improvement in emergency preparedness and response.
As climate change continues to impact water resources and increase the frequency and intensity of extreme weather events, the significance of infrastructure like Gill in mitigating flood risks cannot be understated. Climate enthusiasts and water resource professionals alike may find Gill's data and risk profile a compelling case study in the intersection of dam safety, emergency planning, and climate resilience.
