Summary

This Earth-type dam has a hydraulic height of 12 feet and a structural height of 17 feet, with a total length of 1270 feet. The dam has a normal storage capacity of 53.85 acre-feet and is classified as having low hazard potential.

While the dam's condition assessment is currently not rated, it undergoes inspections every 5 years to ensure its safety and functionality. The dam does not have an emergency action plan (EAP) in place, and there is no information available on risk assessment or management measures. The surrounding area is not considered to be at high risk of inundation, and there are no designated emergency contacts or guidelines for EAP preparation.

Overall, Pivotal Promontory, LLC #4 serves as a crucial infrastructure for irrigation purposes in the region, abiding by state regulations and inspection protocols to maintain its safety standards. Despite lacking certain emergency preparedness measures, the dam's low hazard potential and consistent regulatory oversight contribute to its role in water resource management for the local community.

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.
