Summary
Completed in 1991, this dam stands at a height of 25 feet and has a storage capacity of 24.5 acre-feet. With a surface area of 3.3 acres, this structure serves as a Fish and Wildlife Pond, providing a habitat for local wildlife and offering recreational opportunities for visitors.
Maintained by the Oregon Water Resources Department, Hendrickson is regulated and inspected regularly to ensure its safety and compliance with state regulations. Despite its low hazard potential, the dam has not been assessed for its condition, and emergency action plans are not currently in place. The outlet gates consist of a slide, or sluice gate, allowing for controlled release of water as needed. With no downstream settlement at risk, Hendrickson serves as a peaceful retreat for outdoor enthusiasts to enjoy nature and wildlife in a tranquil setting.
Located in a picturesque area with no downstream settlement to protect, Hendrickson serves as a vital resource for the local ecosystem and a popular spot for recreational activities. As water resource and climate enthusiasts explore the surrounding area, they can appreciate the beauty and functionality of this privately-owned dam, which enhances the quality of life for both wildlife and humans alike.

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.
