Summary
Managed by the Natural Resources Conservation Service, this dam stands at a height of 32 feet and has a storage capacity of 53 acre-feet. With a maximum discharge of 2100 cubic feet per second, Ferdig Number 1 serves the purpose of water resource management in the region.
Despite its age, Ferdig Number 1 has been rated as having a low hazard potential and its overall condition remains unrated. While it meets state regulatory standards for permitting, inspection, and enforcement, the dam lacks recent inspection data, emergency action plans, and updated contact information. As a key infrastructure in the St. Paul District, Ferdig Number 1 plays a crucial role in flood control and water supply management, highlighting the importance of ongoing monitoring and maintenance to ensure its continued effective operation.
For water resource and climate enthusiasts, Ferdig Number 1 presents a fascinating case study of a historic earth dam in South Dakota. With its strategic location on the TR-BAD RIVER and ties to the Natural Resources Conservation Service, this dam serves as a vital piece of infrastructure for water management in the region. As discussions around climate change and water scarcity continue to evolve, Ferdig Number 1 exemplifies the intersection of human-made structures and natural resources, underscoring the ongoing need for sustainable water management practices in the face of evolving environmental challenges.

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.
