Summary
Built in 1985 by the USDA NRCS, the earth dam stands at a height of 40 feet with a structural height of 44 feet and a length of 700 feet. The dam has a normal storage capacity of 46 acre-feet and a maximum storage of 440 acre-feet, providing protection to a drainage area of 4 square miles.
Managed by the Nebraska Department of Natural Resources, Blackwood Creek 62-A has a low hazard potential and is assessed to be in satisfactory condition as of the last inspection in May 2020. With a satisfactory emergency action plan, the dam is equipped to handle potential risks and emergencies effectively. The dam's location in MCCOOK near the TR-BLACKWOOD CREEK stream further highlights its importance in mitigating flood risks in the region.
Water resource and climate enthusiasts will find Blackwood Creek 62-A a crucial infrastructure contributing to the resilience of the local community against flooding events. With its design and construction overseen by the USDA NRCS and regular inspections by the NE DNR, this earth dam stands as a testament to effective flood risk reduction measures implemented in the region. Its low hazard potential, coupled with its satisfactory condition assessment, underscores the importance of maintaining and monitoring such critical infrastructure for the safety and well-being of the surrounding area.

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.
