Summary
Built in 1965 by the US Army Corps of Engineers, this concrete dam stands at a height of 138 feet and has a hydraulic height of 35 feet. With a storage capacity of 609,800 acre-feet and a drainage area of 70,808 square miles, the dam plays a crucial role in managing water levels and controlling the flow of the river.
The dam features two locks, each measuring 1,200 feet in length, and is equipped with Tainter radial gates to regulate water flow. Despite its significant hazard potential and the very high risk assessment, the US Army Corps of Engineers implements rigorous risk management measures to ensure the dam's structural integrity and reduce the potential impact of flooding events. This includes continuous monitoring, emergency action planning, collaboration with local authorities, and regular maintenance to address potential risks and safeguard the surrounding communities.
As a key component of the nation's water resource infrastructure, Captain Anthony Meldahl Locks and Dam exemplifies the critical role that dams play in balancing water management needs while mitigating flood risks. By adhering to strict safety protocols and proactively addressing potential hazards, the dam stands as a testament to the dedication of the US Army Corps of Engineers in safeguarding water resources and protecting communities from the impacts of climate change.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
