Summary

The dam serves the purpose of regulating an unnamed tributary, with a storage capacity of 543 acre-feet and a surface area of 31 acres. Despite its uncontrolled spillway and outlet gates, the dam has been assessed as being in satisfactory condition with a high hazard potential.

Managed by the DAM AND RESERVOIR SAFETY PROG of Missouri, Ed's Lake A Dam is subject to state regulation, permitting, inspection, and enforcement. It falls under the jurisdiction of the Rock Island District of the US Army Corps of Engineers and is represented by Sam Graves (R) in Congress. The dam's risk assessment indicates a moderate level of risk, with measures in place for risk management. The last inspection in September 2015 revealed no significant concerns, with a recommended inspection frequency of 5 years.

For water resource and climate enthusiasts, Ed's Lake A Dam presents an intriguing case study in dam construction and management. With its unique design features and regulatory oversight, the dam offers insights into the challenges and responsibilities associated with maintaining critical infrastructure. As a key component of the local water system, understanding the operations and risks associated with Ed's Lake A Dam can provide valuable lessons for sustainable water resource management in the face of changing climate conditions.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
