Summary
The dam stands at a height of 40 feet and has a storage capacity of 243 acre-feet, primarily used for recreation and water supply purposes. Situated on Gibson Creek, the dam is classified as an earth dam with a buttress core type, ensuring its structural stability.
Despite its importance for water management, Thurber Lake No 5 Dam lacks a spillway and has not been rated for its condition assessment. The dam's hazard potential is listed as "not available," with a high risk assessment rating of 2. While it is privately owned, the dam is subject to state permitting and inspection requirements, although there is no state jurisdiction over its regulation and enforcement. The surrounding area offers a surface area of 5.5 acres for recreational activities, making it a valuable asset in the community.
As climate change continues to impact water resources, the management and maintenance of dams like Thurber Lake No 5 Dam become increasingly vital. With its strategic location on Gibson Creek and its role in providing both recreation and water supply, ensuring the dam's safety and functionality is crucial for the sustainability of the region's water resources. Efforts to assess and address potential risks and hazards associated with the dam will be essential in safeguarding its long-term effectiveness and contributing to the overall resilience of the local water infrastructure.

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.
