Summary
This private-owned earth dam, with a height of 25 feet and a storage capacity of 67 acre-feet, primarily supports agricultural activities in the region. Situated on TR-BRUSH CREEK, the dam plays a vital role in water supply management, ensuring a consistent and reliable source of water for irrigation purposes.
Despite its low hazard potential and current "Not Rated" condition assessment, Carnahan Lake Dam remains an essential infrastructure for water resource management in Camden County, Missouri. The dam's construction did not involve federal agencies or regulations, highlighting its private ownership and operation. With a surface area of 5 acres and a drainage area of 42 square miles, the dam contributes significantly to the local water supply and ecosystem.
While Carnahan Lake Dam may not have undergone recent inspections or maintenance, its strategic location and purpose make it a critical asset for water resource sustainability in the region. As climate change continues to impact water availability and quality, the efficient management of dams like Carnahan Lake becomes increasingly important. As water resource and climate enthusiasts, it is crucial to monitor and support the maintenance and operation of such infrastructure to ensure long-term water security for communities and ecosystems.

Dam Data Reference
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.
