Summary
Built in 1965, this Earth-type dam stands at a height of 33 feet and spans a length of 591 feet, with a storage capacity of 48 acre-feet. Managed by the Natural Resources Conservation Service, the dam is regulated, inspected, and enforced by the South Dakota Department of Environment and Natural Resources, ensuring its safety and compliance with state regulations.
With a low hazard potential and a condition assessment of "Not Rated", Hix Number 1 is a crucial infrastructure for water resource management in the area. Despite lacking specific details on its purposes and associated structures, the dam plays a vital role in flood control, water storage, and ecosystem maintenance along the White River. Its location within the St. Paul District of the US Army Corps of Engineers highlights its importance in maintaining the water resources and climate resilience of the region.
As a key element in the local water management system, Hix Number 1 serves as a testament to the collaboration between private owners, federal agencies, and state regulators in ensuring the safety and effectiveness of water infrastructure. With its strategic positioning and capacity for storage and discharge, the dam contributes to the overall water security and resilience of the Jones County area in South Dakota. As water resource and climate enthusiasts, understanding the significance of structures like Hix Number 1 is essential for ensuring sustainable water management practices 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.
