Summary

This Earth dam stands at a height of 17.5 feet and has a storage capacity of 253 acre-feet. With a surface area of 50 acres, the dam serves a primary purpose that is classified as 'Other', making it an intriguing structure for water resource and climate enthusiasts to explore.

Managed by the Oregon Water Resources Department (OWRD), the Little River Log Pond dam is regulated, permitted, inspected, and enforced by the state agency. Despite its low hazard potential and 'Not Rated' condition assessment, the dam's operational features include slide gates for outlet control. The dam has a history of periodic inspections, with the most recent one conducted in December 2020, and a designated inspection frequency of 6 years.

For those interested in the intersection of water resources and infrastructure, the Little River Log Pond offers a fascinating case study of a privately owned dam in a picturesque location in Douglas County, Oregon. With its unique design, historical significance, and state-regulated status, this dam serves as a valuable asset for studying water management practices, conservation efforts, and the impact of climate change on our water resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
