Summary
The reservoir was completed in 1894 and has a dam height of 24 feet and a length of 300 feet, with a storage capacity of 470 acre-feet. It is situated on Cottonwood Creek and is regulated by the Arizona Department of Water Resources.
Despite being categorized as having low hazard potential, Rogers Reservoir is considered to have a moderate risk level, indicating some potential challenges in terms of its structural integrity and overall management. The reservoir has not been inspected since July 2011, with an inspection frequency of 5 years. While the condition assessment is marked as "Not Rated," the risk assessment suggests that there could be areas of concern that require attention.
As a key element in the water resource infrastructure of Graham, Arizona, Rogers Reservoir serves as a vital resource for agricultural activities in the region. With its historical significance dating back over a century, it is essential for the Arizona Department of Water Resources to ensure proper regulation, inspection, and maintenance to safeguard the reservoir's functionality and durability for years to come.

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.
