Summary
This Earth-type dam stands at a height of 19 feet and stretches 450 feet in length, with a spillway width of 6 feet. The dam's purpose is primarily categorized as "Other," with a fair condition assessment as of November 2016. Despite its fair condition, the dam poses a significant hazard potential, leading to a moderate risk assessment rating.
The dam, completed in an unknown year, holds a normal storage capacity of 0 acre-feet and covers a surface area of 1.1 acres. While the dam is state-regulated and regularly inspected, its emergency action plan status and risk management measures remain unspecified. With a risk assessment rating of moderate, the Hatchery Pond Dam serves as a crucial structure in managing water resources in the area, highlighting the importance of ongoing maintenance and monitoring to ensure its safety and functionality for both water resource and climate enthusiasts.
As a vital component in the local water management infrastructure, Hatchery Pond Dam plays a crucial role in flood control and water supply regulation for the surrounding area. With its significant hazard potential and fair condition, continued monitoring and potential upgrades are essential to mitigate risks and ensure the long-term resilience of this important water resource structure. Water and climate enthusiasts can appreciate the complexity and importance of maintaining and managing dams like Hatchery Pond to support sustainable water resource management in the face of changing climate conditions.

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.
