Summary
It has a normal storage capacity of 60 acre-feet and a maximum storage of 80 acre-feet, serving as a vital resource for water management in the area. The dam is situated on Tr-Crab Creek and is regulated by the Washington Department of Ecology.
Despite its low hazard potential, Taggares Dam No 1 plays a significant role in water resource management and climate resilience efforts in the region. With a drainage area of 0.06 square miles and a maximum discharge of 33 cubic feet per second, the dam contributes to flood control and water supply stability in the surrounding areas. While the dam's condition is currently "Not Rated," it is subject to state inspection, enforcement, and permitting, ensuring its continued safe operation for the community.
Taggares Dam No 1 not only serves as a critical infrastructure for water resource management but also reflects the collaborative efforts between private ownership and state regulatory agencies in ensuring the safety and sustainability of water infrastructure. As a part of the broader network of dams in the region, this earth dam stands as a testament to the importance of proactive monitoring, risk assessment, and emergency preparedness in mitigating potential water-related hazards and ensuring the long-term resilience of water resources in Washington State.

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.
