Summary
Managed by the Arizona Department of Water Resources, this earth dam structure was completed in 1975 and stands at a height of 33 feet, with a length of 580 feet, creating a surface area of 9 acres and a storage capacity of 105 acre-feet. The dam is regulated by the state and undergoes regular inspections to ensure its satisfactory condition, with a significant hazard potential and moderate risk assessment.
The dam's spillway, with a width of 65 feet, is uncontrolled, while the drainage area of Trophy Lake is 2.22 square miles, sourced by the Silver Creek - TR river or stream. While there are no associated locks, the dam serves a primary purpose of recreation, attracting water resource and climate enthusiasts to enjoy its serene surroundings. With a risk management plan in place and regular inspections, Trophy Lake continues to provide a safe and enjoyable experience for visitors, showcasing the importance of responsible dam management in ensuring water resource sustainability for future generations.

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.
