Summary

With a height of 14 feet and a storage capacity of 51 acre-feet, this dam serves a primary purpose other than flood control or water supply. Despite being regulated by the Oregon Water Resources Department and subject to state permitting, inspection, and enforcement, the dam is considered to have a low hazard potential and has not been assessed for its current condition.

Located in Klamath County, the Gilchrist Log Pond does not have a downstream settlement and is managed by private owners. The dam features slide gates for water control and has not undergone any significant modifications since its construction. While the dam is not considered a high-risk structure, its emergency action plan status and risk management measures are unknown. The last inspection in 2018 indicated that the dam's condition was not rated.

For water resource and climate enthusiasts, the Gilchrist Log Pond represents a historic infrastructure along the Little Deschutes River with a modest storage capacity and low hazard potential. As a privately owned dam in Oregon, it operates under state regulations and oversight, but its current condition and emergency preparedness status are not fully assessed. The dam's role in water management and conservation in the region highlights the importance of monitoring and maintaining aging infrastructure for sustainable water resource management in the face of changing climate conditions.

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.
