Tsaile Reservoir Report

Last Updated: April 1, 2026

Tsaile, located in Apache County, Arizona, is home to the Tsaile Creek and the Tsaile Lake, which serve as important water resources for irrigation and recreational purposes.


Summary

The Tsaile dam, completed in 1964 by the Bureau of Indian Affairs, stands at a structural height of 61 feet and has a storage capacity of 8100 acre-feet. The dam, primarily made of earth, is designed to control water flow and prevent flooding in the area.

Despite its important role in water management, the Tsaile dam is classified as having a high hazard potential, indicating the need for regular inspections and maintenance. The dam is under the jurisdiction of the Bureau of Indian Affairs, which oversees its operation, construction, and regulatory compliance. The risk assessment for the dam is rated as very high, highlighting the importance of implementing robust risk management measures to ensure the safety and integrity of the structure. Climate enthusiasts and water resource experts alike can appreciate the complex infrastructure and management challenges associated with the Tsaile dam and its critical role in the local ecosystem.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
