Summary
This private earth dam stands at a height of 20 feet with a storage capacity of 196 acre-feet. While the dam has not been rated for its condition, it is categorized as having a low hazard potential.
Managed by the Department of Natural Resources and Conservation (DNRC), Seven Tree Dam is state-regulated and subject to regular inspections and enforcement measures. Despite lacking specific data on its spillway type and maximum discharge capacity, the dam is crucial for water resource management in the region. Its location at S21 19N 41E makes it a key asset for maintaining water supply and protecting against potential emergencies.
Water resource and climate enthusiasts will find Seven Tree Dam to be a significant structure in the Omaha District, with a rich history dating back to the mid-20th century. While its exact design and construction details may be scarce, its primary purpose of providing essential services to the local community highlights its importance in the broader context of water infrastructure. As efforts to address climate change continue, understanding and maintaining dams like Seven Tree Dam will be crucial for sustainable water management practices in the future.

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.
