Summary
The dam is privately owned and falls under the jurisdiction of the state regulatory agency. With a height of 26.3 feet and a storage capacity of 190 acre-feet, the dam plays a critical role in managing water resources in the region.
The dam is classified as an earth dam with a buttress core type and an uncontrolled spillway. Despite its low hazard potential and moderate risk assessment, the dam's condition is currently not rated. The last inspection was conducted in May 2016, with a recommended inspection frequency of every 5 years. While the dam has not undergone any modifications in recent years, it is important to ensure regular maintenance and monitoring to mitigate any potential risks associated with its operation.
Hill Lake Dam is a vital infrastructure that supports agricultural activities in the area, highlighting the intersection of water resources management and climate resilience. As climate change continues to impact water availability and quality, the proper management and upkeep of dams like Hill Lake Dam are crucial for ensuring sustainable water usage and safeguarding against potential emergencies. Efforts to enhance risk assessment and management measures for the dam will be essential in maintaining its functionality and resilience in the face of evolving climate challenges.

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.
