This earth dam stands at a height of 25 feet and has a storage capacity of 107 acre-feet. The dam overlooks the TR-Osage River and serves as a popular spot for outdoor enthusiasts seeking recreational activities such as fishing and boating.
Despite its recreational value, Pinnell Lake Dam poses a high hazard potential due to its condition assessment being labeled as "Not Rated." The dam's emergency action plan (EAP) status is also unclear, raising concerns about the readiness and preparedness for potential emergencies. With a drainage area of 315 square miles, the dam plays a crucial role in managing water resources in the region, emphasizing the importance of regular inspections and maintenance to ensure public safety and environmental protection.
As climate change continues to impact water resources, the management and maintenance of dams like Pinnell Lake Dam become increasingly vital. With its location in the St. Louis District and oversight by private owners, the dam's role in water regulation and recreation underscores the need for proactive risk assessment and management measures. As water resource and climate enthusiasts, staying informed about the condition and management of dams like Pinnell Lake Dam is essential for preserving the sustainability and safety of water systems in the face of changing environmental conditions.
