Creosote Detention Dam Reservoir Report
Last Updated: December 5, 2025
Creosote Detention Dam, located in Solomon, Arizona, along the San Simon River, was completed in 1981 by the Bureau of Land Management to primarily reduce flood risks in the area.

Summary
This gravity dam stands at a hydraulic height of 20 feet and a structural height of 25 feet, with a length of 1507 feet. It has a storage capacity of 379 acre-feet, with a normal storage level of 205.14 acre-feet, covering a surface area of 22.2 acres and draining an area of 3.88 square miles.
Despite its low hazard potential, the dam's condition assessment is rated as poor, indicating a need for maintenance or upgrades. The last inspection was conducted in February 2012, with an inspection frequency of every 5 years. The risk assessment for the dam is moderate, and it is not regulated by the state. This essential structure plays a crucial role in managing water resources and mitigating flood risks in the region, highlighting the importance of investing in its maintenance and upkeep to ensure its continued effectiveness and safety for the surrounding community and environment.

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.
