Summary
Completed in 1938 by the USDA Forest Service, this dam serves multiple purposes including fire protection, stock watering, and small fish pond management. Situated on Little Thunder Creek, the dam has a height of 18 feet and a length of 530 feet, with a storage capacity of 197 acre-feet.
Despite its low hazard potential and moderate risk assessment, Thunder Basin No 10 has not been rated for its condition as of the last inspection in 2008. The dam features an uncontrolled spillway with a width of 50 feet, and is regulated and inspected by the USDA Forest Service. While the dam does not currently meet state jurisdiction guidelines, it is equipped for state permitting, inspection, and enforcement, ensuring its continued safety and functionality for the surrounding area.
With a drainage area of 25 square miles and a maximum discharge of 2715 cubic feet per second, Thunder Basin No 10 plays a crucial role in managing water resources in the region. As a key component of the local ecosystem and recreational opportunities, this dam underscores the importance of sustainable water management practices in the face of changing climate conditions.

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.
