Summary
Completed in 1967, this earth dam stands at a height of 29 feet and stretches 350 feet in length, with a storage capacity of 91 acre-feet. Situated on Spring Creek in the St. Paul District, the dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity and safety.
Despite its relatively low hazard potential, Blomstrom Dam is in poor condition and requires attention to improve its overall assessment. The last inspection in April 2018 highlighted the need for maintenance and potential mitigation measures to address any risks associated with the dam. With a drainage area of 1.3 square miles and a maximum discharge of 227 cubic feet per second, the dam plays a crucial role in water resource management in the region, emphasizing the importance of timely maintenance and monitoring to prevent any potential hazards.
As an essential component of the local water infrastructure, Blomstrom Dam serves as a critical resource for fire protection, livestock, and recreational activities. With its location in a remote area of Nebraska, the dam provides valuable water storage capacity and flood control capabilities, ensuring the safety and sustainability of the surrounding community. Moving forward, proactive measures and investments in maintenance and upgrades will be essential to safeguard the dam's long-term functionality and resilience in the face of changing climate conditions.

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.
