Summary
Constructed in 1936 by Ducks Unlimited and an unknown designer, this earth dam stands at a height of 11 feet with a length of 1800 feet, offering a storage capacity of 4027 acre-feet. With a controlled spillway and a low hazard potential, the dam is regulated and inspected by the U.S. Fish and Wildlife Service to ensure its structural integrity and safety.
Despite its key role in water management, Stoney Slough Pool 2 Dam is currently rated as being in poor condition, with a very high risk assessment. The last inspection in 2013 revealed the dam's need for structural improvements, leading to a modification in the same year. Although the dam has a limited hazard potential, its risk management measures and overall condition require immediate attention to prevent any potential failures that could impact the surrounding environment and wildlife.
As a critical component of the local ecosystem, Stoney Slough Pool 2 Dam's functionality and safety are paramount in maintaining the delicate balance of water resources and wildlife habitats in the region. With proper maintenance and upgrades, this dam can continue to serve its primary purpose effectively while safeguarding the surrounding environment from potential risks and hazards associated with its current condition.

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.
