Summary

Built in 1928, this dam stands at a height of 30 feet and has a storage capacity of 332 acre-feet. With a surface area of 11 acres and a drainage area of 13 square miles, this dam plays a crucial role in providing water to the local community.

Despite its age, Stacy Park Reservoir Dam has not been rated for its condition and is classified as having a high hazard potential. The last inspection of the dam took place in October 1980, and it is not regularly inspected. While there are no associated structures, the dam is in a buttress core type with an unlisted/unknown foundation. It is essential for water resource and climate enthusiasts to monitor the condition of this dam to ensure the safety and security of the surrounding area.

With its unique design and history, Stacy Park Reservoir Dam serves as a reminder of the importance of maintaining and monitoring essential water supply structures. As a local government-owned facility, it is crucial to prioritize the safety and upkeep of this dam to prevent any potential risks or hazards. Water resource and climate enthusiasts should advocate for regular inspections and maintenance to ensure the continued reliability and functionality of Stacy Park Reservoir Dam for years to come.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
