Summary
Standing at a height of 23.2 feet with a length of 310 feet, the dam has a storage capacity of 244.6 acre-feet, making it a crucial component in managing water resources in the area. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity and safety.
With a low hazard potential and a condition assessment of "Not Rated," Steffensen Dam plays a vital role in water management for the surrounding community. Despite not having an Emergency Action Plan (EAP) in place, the dam meets regulatory guidelines and is subject to regular risk assessments to mitigate any potential hazards. The dam's location on TR-Sand Canyon and its association with the Omaha District of the US Army Corps of Engineers highlight its importance in providing essential water resources and protection for the local ecosystem.
As a key structure in water resource management, Steffensen Dam serves as a testament to the innovative engineering practices employed in the mid-20th century. Its earth core and stone foundation stand as a testament to the durability and longevity of the construction. With its strategic location and crucial role in providing water for fire protection and livestock, Steffensen Dam continues to be a focal point for water resource and climate enthusiasts interested in sustainable infrastructure development and management.

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.
