Summary
Constructed in 1990, this lagoon system serves as a storage facility for potato waste, with a maximum storage capacity of 900 acre-feet and a normal storage capacity of 750 acre-feet. The dam has a structural height of 17 feet and a hydraulic height of 33 feet, providing low hazard potential according to its classification.
Situated in Adams County, Washington, the Carnation Potato Waste Lagoon System is regulated by the Washington Department of Ecology and is subject to state permitting, inspection, and enforcement. The dam is designed to withstand potential risks associated with its operations, although its condition has not been formally assessed. Despite its low hazard potential, the lagoon system plays a crucial role in managing waste from potato processing, showcasing how innovative engineering solutions can address environmental challenges in agricultural settings.
With its focus on waste management and environmental sustainability, the Carnation Potato Waste Lagoon System exemplifies the intersection of water resource management and climate-conscious practices. As a key component of the local agricultural infrastructure, this earth dam highlights the importance of responsible waste disposal practices and the role that privately owned water resources play in supporting sustainable agriculture. As enthusiasts of water resources and climate action, understanding the design and operation of facilities like the Carnation Potato Waste Lagoon System can provide valuable insights into the intersection of agriculture, water management, and environmental conservation.

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.
