Summary
Millard and Associates Inc. and USDA NRCS. Completed in 1969, this Earth-type dam serves the primary purpose of irrigation along Jakes Creek. With a hydraulic height of 18 feet and a structural height of 22 feet, the dam stands at 44 feet tall and stretches 1315 feet in length, holding a maximum storage capacity of 472 acre-feet.
Despite its low hazard potential, the dam's condition assessment is rated as poor, indicating a need for maintenance and upkeep. The last inspection in June 2021 revealed this, prompting a moderate risk assessment of 3. With an uncontrolled spillway type and a slide (sluice gate) outlet gate, the dam's operation and safety measures may need to be reviewed to ensure its continued functionality and structural integrity. As a vital water resource for irrigation, Boies Reservoir Dam's importance in sustaining agricultural activities in the region cannot be understated, making its maintenance and risk management crucial for water resource and climate enthusiasts.

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.
