Summary

This earth dam stands at a hydraulic height of 25 feet and a structural height of 20 feet, with a length of 370 feet and a storage capacity of 30 acre-feet. The dam is primarily made of stone with a soil foundation and is regulated by the Washington Department of Ecology.

Despite its low hazard potential, Blazing Tree Ranch Pond 6 Dam has not been rated for its condition assessment. It currently does not have an Emergency Action Plan (EAP) in place, and there is limited information available regarding its risk assessment and management measures. The dam overlooks Tr-Garrison Bay and has a maximum discharge capacity of 100 cubic feet per second, making it a crucial component in the local water resource infrastructure.

As an important structure for water management in the region, Blazing Tree Ranch Pond 6 Dam showcases the intersection of human ingenuity and environmental stewardship. With its focus on irrigation purposes and its state-regulated status, this dam stands as a testament to the ongoing efforts to balance water resource utilization and conservation in the face of climate change challenges.

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.
