Summary
The primary purpose of this Earth dam structure, completed in 1994, is for irrigation, with secondary recreational uses. With a structural height of 40 feet and a length of 3278 feet, this reservoir has a storage capacity of 2812 acre-feet.
Despite being classified as a high hazard potential dam, Ganado Lake has not undergone a recent condition assessment, posing potential risks to the surrounding area. The emergency action plan for this site was last revised in 2012, indicating a need for updated safety measures. While the dam is not under the jurisdiction of state regulatory agencies, it is subject to federal oversight from the Bureau of Indian Affairs.
Water resource and climate enthusiasts interested in Ganado Lake can appreciate its importance for irrigation in the region, as well as the potential risks associated with its high hazard classification. With a focus on sustainable water management practices and safety protocols, the management of Ganado Lake by the Bureau of Indian Affairs plays a crucial role in ensuring the safety and reliability of this vital water resource for the community of Ganado and surrounding areas in Arizona.

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.
