Summary
Standing at a height of 19 feet, the dam has a storage capacity of 110 acre-feet. The dam is regulated by the Oregon Water Resources Department and undergoes regular inspections to ensure its structural integrity.
The dam features slide (sluice gate) outlet gates and is classified as having a low hazard potential. Despite being not rated for its condition assessment, Turner Dam has been inspected every six years, with the last inspection conducted in July 2014. While the dam has not undergone any modifications or improvements in recent years, it continues to serve its purpose of providing water supply to the surrounding area.
Turner Dam, situated in the Portland District, plays a crucial role in water resource management in the region. With its strategic location and reliable performance, the dam contributes to ensuring a stable water supply for the community. As water resource and climate enthusiasts, understanding the infrastructure and operations of Turner Dam can provide valuable insights into the management of water resources in 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.
