Summary
With a height of 30 feet and a length of 3960 feet, this earth dam serves the primary purpose of irrigation, providing a storage capacity of 250 acre-feet. The dam is situated on Tr- Cabin Creek in Capitol, Montana, and is managed by the Natural Resources Conservation Service.
Despite its age, the condition assessment of Ding Dong is currently listed as "Not Available," with a significant hazard potential. The dam has not undergone recent inspections, and emergency preparedness measures such as an Emergency Action Plan (EAP) are lacking. As water resource and climate enthusiasts, it is crucial to monitor the maintenance and safety of dams like Ding Dong to ensure the protection of surrounding communities and the efficient use of water resources for irrigation purposes.
As advocates for sustainable water management, it is important to highlight the need for regular inspections, maintenance, and emergency preparedness measures for dams like Ding Dong. By staying informed and involved in the oversight of critical water infrastructure, we can help mitigate potential risks and safeguard the vital resources that these structures provide for agriculture and local communities.

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.
