Completed in 1972, this dam stands at a height of 19 feet and has a storage capacity of 93 acre-feet. With a surface area of 5 acres and a controlled spillway, the dam has a low hazard potential and a very high risk assessment rating.
Managed by the Oklahoma Water Resources Board (OWRB), this dam has state jurisdiction and is subject to state regulations for permitting, inspection, and enforcement. The primary purpose of SCS-Maysville Laterals Site-H02 is flood risk reduction, with a valve outlet gate for water control. Despite being last inspected in 1980, with an inspection frequency of 5 years, the dam's condition is currently not rated.
The site's risk management measures, emergency action plan (EAP), and inundation maps are not updated, with no assigned DSAC date for risk assessment. With its strategic location and critical role in flood control, SCS-Maysville Laterals Site-H02 serves as a vital water resource infrastructure in the region, protecting communities downstream from potential flooding events.
