Summary
Managed by the local government, this earth dam structure was completed in 1980 and stands at a height of 58 feet, with a storage capacity of 6,300 acre-feet. The reservoir offers a surface area of 380 acres and draws its water from the TRIB SOUTH FORK BLACKWATER stream, serving the surrounding community with essential water supply needs.
With a spillway width of 150 feet and a maximum discharge capacity of 5,479 cubic feet per second, Holden New City Reservoir is equipped to handle potential high hazard levels. The dam is inspected every two years, with the last assessment in October 2016 deeming its condition satisfactory. Despite the moderate risk assessment, the reservoir's risk management measures and emergency action plans are up to date, ensuring the safety and well-being of the area in case of emergencies. Water resource and climate enthusiasts will appreciate the strategic design and efficient operation of this vital reservoir in Johnson County, Missouri.

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.
