Summary
Completed in 1998 by the US Army Corps of Engineers, this Earth-type dam stands at a height of 53 feet with a hydraulic height of 50 feet, serving the primary purpose of flood risk reduction along the Harland Creek. With a storage capacity of 13,686 acre-feet and a surface area of 200 acres, this structure plays a crucial role in managing water levels and mitigating flood hazards in the region.
The dam, with a spillway width of 400 feet, has a significant hazard potential and undergoes inspections every 5 years to ensure its structural integrity. The US Army Corps of Engineers actively manages flood-related risks associated with the dam by monitoring its condition, prioritizing risk-reduction activities, and engaging with local emergency managers and the public to raise awareness and preparedness for potential emergencies. With a comprehensive Emergency Action Plan in place, the dam is regularly maintained and repaired to function effectively in times of need. As part of ongoing risk management measures, the USACE continuously updates its emergency plans and collaborates closely with local authorities to ensure the safety and resilience of the surrounding 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.
