Constructed in 1914, this earth dam stands at a height of 11 feet and has a maximum storage capacity of 400 acre-feet. The reservoir covers an area of 87.8 acres, with a drainage area of 3.62 square miles and a maximum discharge rate of 150 cubic feet per second.
Managed by the Oregon Water Resources Department, Beer S Reservoir has a low hazard potential and is not currently rated for its condition. The dam has a history of regular inspections, with the last one conducted in November 2020. Despite its age, the facility remains in good standing and meets state regulatory standards for permitting, inspection, and enforcement. The reservoir serves as a vital resource for the local community, supporting agricultural activities in the region.
With its picturesque location in Riverside, Oregon, Beer S Reservoir is a crucial water source for sustaining agricultural operations in the area. As climate change continues to impact water resources, facilities like Beer S Reservoir play a vital role in ensuring water security for the surrounding communities. As enthusiasts for water resources and climate change, monitoring the condition and management of reservoirs like Beer S is essential for sustainable water use in the face of a changing climate.

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.
