Summary
Completed in 1962, this earth dam stands at 25 feet high and spans 300 feet in length. The reservoir has a storage capacity of 70 acre-feet, with a normal storage level of 42 acre-feet, serving purposes such as fire protection, stock watering, and small fish pond habitat.
With its proximity to the TR-DRY ARMELLS CREEK, Hey Joe Reservoir plays a crucial role in water resource management in the area. The spillway, with a width of 50 feet, ensures controlled water discharge during high flow events, minimizing flood risks. The reservoir has a low hazard potential and a moderate risk assessment rating, highlighting its importance in mitigating potential water-related hazards in the region.
While Hey Joe Reservoir is not currently rated for its condition, it remains a vital infrastructure for water supply and ecosystem support. As a key component of the local water management system, the reservoir provides essential services for wildlife, agriculture, and emergency water needs. Its strategic location and design by USDA NRCS underscore the importance of sustainable water resource management practices in the face of changing climate conditions.

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.
