Summary
This earth dam stands at a height of 12 feet and stretches 680 feet in length, with a storage capacity of 229 acre-feet. The dam, built on PASS CREEK, is regulated by the South Dakota Department of Environment and Natural Resources, and is classified as having low hazard potential.
Despite not being rated for its condition, Huddleston Dam poses a moderate risk with a risk assessment score of 3 out of 5. The dam features an uncontrolled spillway with a width of 100 feet and no outlet gates. While the dam has not been inspected recently, it is stated to undergo regular inspections, permitting, and enforcement by the state agency. The surrounding area has a drainage area of 16 square miles and can discharge up to 1350 cubic feet per second.
For water resource and climate enthusiasts, Huddleston Dam serves as an interesting case study of a small-scale earth dam in South Dakota. With its unique design and moderate risk assessment, the dam highlights the importance of regular monitoring and maintenance to ensure the safety and efficiency of water management infrastructure. As climate change continues to impact water resources, understanding the state regulations and management practices of dams like Huddleston is crucial for sustainable water resource management in the future.

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.
