Summary
This earth dam, completed in 1991, stands at a height of 37 feet and serves the primary purpose of irrigation, with a storage capacity of 2978 acre-feet and a normal storage level of 286 acre-feet. The dam spans 1157 feet in length and covers a surface area of 50 acres, contributing to the efficient management of water resources in the region.
Operated by the NE DNR, Swan Creek 27 is subject to state regulations and inspections, ensuring its structural integrity and compliance with safety standards. With a low hazard potential and satisfactory condition assessment, the dam plays a crucial role in water supply and management for the surrounding area. The dam's maximum discharge capacity of 3766 cubic feet per second further highlights its significance in mitigating potential flood risks and supporting agricultural activities.
As part of the larger water management system, Swan Creek 27 contributes to the overall sustainability and resilience of the region's water resources. With a strategic location in Jefferson County, Nebraska, and its affiliation with the Omaha District, the dam exemplifies the collaborative efforts between local government agencies and the USDA NRCS to safeguard water supplies and support agricultural needs in the area. The dam's consistent monitoring, regular inspections, and adherence to state regulations underscore its importance in addressing the water resource and climate challenges faced by the community.

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.
