Summary
This dam stands at a height of 29 feet, with a hydraulic height of 27 feet and a structural height of 35 feet, providing a vital storage capacity of 998 acre-feet. With a normal storage capacity of 91 acre-feet and a drainage area of 3.8 square miles, this dam plays a crucial role in managing water resources and mitigating flood risks in the area.
Despite its importance, Bowman-Spring Branch 2-A currently faces challenges as it has been assessed with a poor condition and a low hazard potential. The dam's last inspection in May 2019 highlighted the need for improvement, raising concerns about its structural integrity. As a state-regulated dam under the jurisdiction of the Nebraska Department of Natural Resources, ongoing maintenance and inspection are essential to ensure the safety and efficiency of this key water infrastructure.
As water resource and climate enthusiasts, it is crucial to monitor and support the maintenance and rehabilitation efforts of dams like Bowman-Spring Branch 2-A. By recognizing the vital role these structures play in water management and flood prevention, we can contribute to preserving our water resources and enhancing resilience to climate-related challenges in Nebraska and beyond.

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.
