Summary
Constructed in 1984 by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. With a height of 47 feet and a storage capacity of 254 acre-feet, the dam covers a surface area of 9.1 acres and drains an area of 0.16 square miles.
Despite being rated as low hazard potential and not yet assessed for condition, the site poses a moderate risk due to its critical role in managing water resources and potential impact on downstream areas. While there are currently no outlet gates or locks associated with the dam, its uncontrolled spillway and soil foundation ensure its functionality in emergency situations. The site has not been inspected in recent years, highlighting the need for regular monitoring and maintenance to ensure its continued effectiveness in flood control and water conservation efforts.
As part of the Omaha District, the Waubonsie Creek Watershed Site 3-1-2 stands as an important infrastructure for water management in the region. With its strategic location along the Waubonsie Creek, this dam plays a crucial role in mitigating flood risks and providing essential water resources for the local community. Moving forward, continued investment in inspections, risk assessments, and maintenance will be key to preserving the functionality and effectiveness of this vital water resource infrastructure.

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.
