Summary

Constructed in 2007 by USDA NRCS, this Earth-type dam stands at a hydraulic height of 15.13 feet and serves as a crucial component in managing dairy waste in the area. With a storage capacity of 31 acre-feet and a surface area of 3.4 acres, this dam plays a vital role in maintaining the environmental balance in the region.

The dam, with a high hazard potential and fair condition assessment, is regulated by the Washington Department of Ecology and undergoes regular inspections every 5 years. With a normal storage capacity of 30.8 acre-feet, the dam helps prevent potential environmental hazards and supports sustainable dairy farming practices. Despite its age, the dam continues to function effectively, showcasing the importance of proper waste management infrastructure in mitigating climate and water resource challenges.

As a key structure in the state's regulatory framework, Edaleen Dairy Waste Storage Pond No 3 represents a successful collaboration between private ownership and state oversight. Its strategic location in Whatcom County, Washington, highlights the significance of responsible waste management practices in protecting water resources and the environment. With continued monitoring and maintenance, this dam serves as a testament to the importance of sustainable infrastructure in addressing climate and water-related concerns.

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.
