Summary
Standing at a height of 21 feet and with a maximum storage capacity of 210 acre-feet, this dam plays a crucial role in providing water resources for agricultural activities in the region. Despite being unregulated by the state, the dam is inspected regularly, with the last inspection dating back to February 2003, and has a low hazard potential.
With a surface area of 20 acres and a drainage area of 0, Pennington Irrigation Lake Dam serves as a vital water resource for the local community. The dam features an uncontrolled spillway and outlet gates, ensuring efficient water management for irrigation purposes. While the condition assessment is currently not rated, the risk assessment is moderate, indicating the need for continued monitoring and risk management measures to ensure the safety and effectiveness of the dam in the face of changing climate conditions.
Overall, Pennington Irrigation Lake Dam stands as a testament to the importance of water resource management in the face of climate variability. With its strategic location and design, the dam plays a crucial role in supporting agricultural activities in the region, highlighting the significance of sustainable water infrastructure for addressing the challenges posed by a changing climate. As efforts continue to ensure the safety and functionality of the dam, it remains a key asset for water resource and climate enthusiasts alike.

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.
