Summary
With a primary purpose of irrigation, these lagoons were completed in 1984 and have a storage capacity of 115 acre-feet. The lagoons cover a surface area of 28 acres and have a dam height of 12 feet, providing essential water management in the region.
Located off-channel near the city of Boardman, these sewage lagoons play a vital role in maintaining water quality and availability for agricultural irrigation. The lagoons have been regulated and inspected by the Oregon Water Resources Department, ensuring compliance with state regulations. With a low hazard potential and not yet rated condition assessment, the Boardman Sewage Lagoons continue to support the local community's water needs.
Despite their low hazard potential, the lagoons undergo regular inspections every 6 years to assess their condition and ensure efficient operation. The facility's emergency action plan status and risk management measures are currently not disclosed, but the lagoons remain a key component of water resource management in the region. For water resource and climate enthusiasts, the Boardman Sewage Lagoons represent a vital infrastructure supporting irrigation and water management in Morrow County, Oregon.

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.
