Summary
Designed by the USDA NRCS, this earth dam stands at a height of 21 feet and spans a length of 520 feet. With a storage capacity of 94 acre-feet, the dam serves multiple purposes including flood risk reduction and other water resource management functions.
Managed by the Nebraska Department of Natural Resources, Boelter Dam has a low hazard potential and is currently assessed to be in fair condition as of the last inspection in November 2019. The dam features stone core construction and soil foundation, with a structural height of 23 feet. Despite its modest size, the dam plays a crucial role in maintaining water levels and mitigating flood risks in the region, with a maximum discharge capacity of 483 cubic feet per second.
Although the dam does not have a spillway or outlet gates, its presence helps regulate water flow and protect downstream areas from potential flooding events. With a designated inspection frequency and emergency action plan in place, Boelter Dam remains a key component of water resource management in the area, ensuring the safety and stability of its surrounding communities and environment.

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.
