Summary
Built in 1977, the dam stands at a height of 37 feet and has a storage capacity of 132 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," the dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality.
Situated on the TR-Ponca Creek, Blum Dam plays a crucial role in water resource management in the area, with a maximum discharge capacity of 350 cubic feet per second. The dam's earth type construction with stone core and soil foundation contributes to its stability and longevity. Despite its modest size, the dam covers a surface area of 6 acres and serves a drainage area of 2 square miles, providing essential water supply for agricultural activities in the region.
Managed by a private entity, Blum Dam is a key component of the local irrigation infrastructure, contributing to the overall water resource management in Nebraska. With its consistent performance and adherence to regulatory standards, the dam ensures a reliable water supply for the surrounding area while maintaining a low risk profile. Water resource and climate enthusiasts will appreciate the strategic significance of Blum Dam in sustaining agricultural activities and supporting the environmental ecosystem of the region.

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.
