Summary
Built in 1965, this earth dam stands at a hydraulic height of 25 feet and a structural height of 20 feet, with a length of 280 feet. The dam has a storage capacity of 100 acre-feet and covers a surface area of 12.8 acres, serving the surrounding area with water for irrigation and recreation.
Managed by the Washington Department of Ecology, the dam is regulated and inspected regularly to ensure its safety and compliance with state regulations. With a low hazard potential and a current condition assessment of "Not Rated," the dam provides a crucial water resource for the region while posing minimal risk to nearby communities. While the dam has not been modified in recent years and lacks certain emergency preparedness measures like an Emergency Action Plan (EAP), it remains a key infrastructure for water management in the area.
Despite its modest size and limited associated structures, Blazing Tree Ranch Pond 5 North Dam plays a vital role in the local water supply system, contributing to the irrigation needs of the community. Its presence on Tr-Garrison Bay underscores the importance of sustainable water management practices in the face of changing climate conditions. As climate enthusiasts and water resource professionals continue to monitor and protect our water infrastructure, dams like this serve as essential components of a resilient and adaptable water resource system.

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.
