Summary
Built in 1953 by designer T.H. Baldwin, this structure stands at a height of 20 feet with a hydraulic height of 15 feet and a length of 350 feet. Despite its low hazard potential, Donahue is currently assessed to be in poor condition, highlighting the need for maintenance and repairs to ensure its structural integrity.
With a storage capacity of 119 acre-feet and a normal storage level of 56 acre-feet, Donahue plays a crucial role in water resource management for the surrounding area. The dam also serves secondary purposes such as fire protection, stock watering, and small fish pond maintenance. Operating under state jurisdiction and regulatory oversight, Donahue is subject to regular inspections to uphold safety standards and mitigate any potential risks associated with its condition.
Although Donahue's risk assessment is moderate, stakeholders should prioritize implementing risk management measures to address the dam's poor condition and ensure its long-term functionality. Given its significance in irrigation and water storage, proactive maintenance and emergency preparedness are essential to safeguarding this vital water resource for the community and maintaining a sustainable water supply in the region.

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.
