Summary
Constructed in 1997, this earth dam stands at a height of 27 feet with a structural height of 37 feet and a length of 790 feet. It has a storage capacity of 145 acre-feet and covers a surface area of 8.4 acres, with a drainage area of 2.9 square miles. The dam is regulated by the Arizona Department of Water Resources and undergoes regular inspections, with the last one conducted in April 2012.
Despite being rated as having a low hazard potential, Stockton Hill faces a moderate risk due to its location and design characteristics. The dam features an uncontrolled spillway with a width of 210 feet and has a maximum discharge capacity of 2910 cubic feet per second. Although the condition assessment is listed as "Not Rated," the dam is deemed to meet safety guidelines. Emergency action plans and risk management measures are not specified, indicating a potential area for improvement in ensuring the safety and resilience of the structure in the face of climate-related challenges.
Overall, Stockton Hill provides a valuable recreational resource in Mohave County, Arizona, while also serving as a reminder of the importance of maintaining and monitoring water infrastructure in the context of changing climate conditions. With its regulated status, regular inspections, and moderate risk level, this dam represents a crucial piece of the water management puzzle in the region, highlighting the need for ongoing vigilance and preparedness in safeguarding water resources for the future.

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.
