Summary
Completed in 1978, this earth dam reservoir serves primarily for irrigation purposes, with a storage capacity of 400 acre-feet and a maximum discharge of 1120 cubic feet per second. The reservoir spans an area of 2 acres and is situated along the Grindstone Creek, making it a vital water source for the surrounding agricultural community in Paulina.
With a low hazard potential and a condition assessment that is currently not rated, Layton #2 Reservoir plays a crucial role in water management and irrigation within the region. The reservoir features a slide (sluice gate) outlet gate and has a structural height of 23 feet, providing necessary water control for the area's agricultural needs. Despite its modest size, the reservoir's strategic location and reliable water supply make it an essential component of the local water infrastructure.
Managed by the Oregon Water Resources Department and subject to state regulations and inspections, Layton #2 Reservoir exemplifies responsible water resource management. Its construction and operation align with state permitting and enforcement guidelines, ensuring the safety and sustainability of the reservoir for both agricultural and environmental purposes. For water resource and climate enthusiasts, Layton #2 Reservoir stands as a testament to efficient water utilization and management practices in the face of changing climatic conditions.

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.
