Summary
With a structural height of 38 feet and a hydraulic height of 27 feet, this dam holds back the waters of the Niobrara River to create a lake with a normal storage capacity of 32 acre-feet. The dam spans 214 feet in length and covers a surface area of 4 acres, providing a picturesque setting for outdoor activities.
Managed by the Nebraska Department of Natural Resources, Hull Lake Dam has a low hazard potential and a fair condition assessment as of May 2017. The dam boasts a maximum discharge capacity of 1250 cubic feet per second and is equipped with inspection and enforcement mechanisms to ensure its safety and functionality. While the dam has not undergone any modifications in recent years, it is subject to regular inspections every 5 years to maintain its integrity and compliance with state regulations.
For water resource and climate enthusiasts, Hull Lake Dam presents an opportunity to appreciate the intersection of human infrastructure and natural landscapes. As a vital component of the local ecosystem and a recreational hub for residents and visitors, this dam exemplifies the importance of sustainable water management practices in mitigating environmental risks and enhancing community well-being. By understanding and supporting initiatives to maintain and improve the resilience of dams like Hull Lake, enthusiasts can contribute to the conservation and preservation of water resources for future generations to enjoy.

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.
