Summary
With a height of 21 feet and a length of 750 feet, this dam serves as a crucial structure for the management of the TR-CHEYENNE river or stream. The dam has a maximum storage capacity of 205 acre-feet and a normal storage capacity of 150 acre-feet, making it an essential resource for water conservation in the region.
Managed by the Natural Resources Conservation Service, Carl Humphrey Dam No.1 is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets the necessary inspection, enforcement, and permitting requirements. Despite being classified as having a low hazard potential and not rated for its condition assessment, the dam plays a vital role in flood control and water supply for the surrounding area. With no associated structures and a lack of emergency preparedness assessments, there is room for improvement in ensuring the safety and efficiency of this dam for future climate challenges.
In the political landscape, Carl Humphrey Dam No.1 falls under the jurisdiction of Congressman Dusty Johnson (R) and the Omaha District of the US Army Corps of Engineers. While the dam has not been modified in recent years and lacks detailed risk assessment and management measures, it remains a key infrastructure for water resource management and climate resilience efforts in South Dakota. As water resource and climate enthusiasts, it is essential to monitor and advocate for the maintenance and enhancement of dams like Carl Humphrey Dam No.1 to ensure the sustainable management of water resources in the face of changing environmental conditions.

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.
