Summary
This offstream Earth dam, with a structural height of 15 feet and a hydraulic height of 15 feet, has a storage capacity of 165 acre-feet and covers an area of 8.5 acres. Managed by the Washington Department of Ecology, the dam is regulated by the state and undergoes regular inspections to ensure its safety and functionality.
Situated in Franklin County, Washington, this low hazard dam plays a crucial role in providing water for agricultural irrigation in the region. Although not rated for its condition assessment, the dam has not experienced any significant modifications or incidents. With a state jurisdiction and regulatory agency overseeing its operations, Bernsens 810 Reservoir Dam No 2 serves as a vital infrastructure for water resource management in the area.
Owned by the state and falling under the purview of the Walla Walla District of the US Army Corps of Engineers, this dam represents a key component of the local water infrastructure. With a focus on irrigation and a history of serving the community since its completion over four decades ago, Bernsens 810 Reservoir Dam No 2 stands as a testament to the importance of water resource management and climate resilience in the region.

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.
