Summary
This earth dam serves as a crucial water supply source with a storage capacity of 108 acre-feet. Although it lacks a spillway, the dam's primary purpose is to provide water for the surrounding area, making it essential for both agricultural and residential needs.
Despite being privately owned and not regulated by the state, Indian Tank Dam poses a high risk due to its lack of hazard potential assessment and condition rating. With no emergency action plan in place, the dam's safety and stability remain uncertain. The structure's risk management measures and overall risk assessment are currently unknown, raising concerns about its ability to withstand potential climate-related challenges and ensure the safety of downstream communities.
For water resource and climate enthusiasts, Indian Tank Dam represents a case study in the need for improved infrastructure monitoring and risk management. As climate change continues to impact water resources, the importance of assessing and addressing the vulnerabilities of dams like Indian Tank becomes increasingly urgent. By implementing safety measures and emergency plans, stakeholders can work towards ensuring the resilience of vital water supply structures in the face of evolving environmental threats.

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.
