Summary

Owned privately, the dam is regulated by the Washington Department of Ecology and plays a crucial role in controlling the flow of Tr-Crab Creek. With a hydraulic height of 14 feet and a structural height of 12 feet, the earth dam has a storage capacity of 135 acre-feet and a drainage area of 0.06 square miles.

Despite being classified as a low hazard potential structure, Taggares Dam No 2 is not currently rated for its condition assessment. The dam's primary purpose is listed as 'Other', indicating its versatility in serving various water resource needs. With a maximum discharge capacity of 33 cubic feet per second, the dam contributes to flood control and irrigation in the surrounding area. While specific details such as spillway type and outlet gates are not provided, the dam's strategic location and design make it an essential component of the local water infrastructure.

Managed by private owners and meeting state regulations for inspection and enforcement, Taggares Dam No 2 stands as a testament to the importance of effective water resource management in the face of changing climate patterns. As climate enthusiasts and water resource stakeholders continue to monitor and assess the impact of climate change on water availability, dams like Taggares Dam No 2 play a crucial role in adapting to and mitigating the challenges posed by a changing environment. With its low hazard potential and key regulatory oversight, this dam exemplifies the intersection of water resource management and climate resilience in the Pacific Northwest.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
