Summary
Completed in 1979, the dam stands at a structural height of 145 feet and has a hydraulic height of 30 feet. It serves primarily as a flood control structure along the TR-Mulberry Fork river, with a storage capacity of 3,120 acre-feet.
Despite its significant hazard potential and lacking a condition assessment rating, Rattlesnake Dam has not been regulated or inspected by the state. The dam does not fall under the jurisdiction of any state regulatory agency, highlighting potential gaps in oversight and maintenance. With a maximum discharge capacity of 784 cubic feet per second, the dam plays a crucial role in mitigating flood risks in the region.
As water resource and climate enthusiasts, understanding the operational and emergency response protocols for Rattlesnake Dam is crucial. While the dam lacks specific risk assessment and management measures, its presence as a key flood control structure underscores the importance of ensuring its structural integrity and maintenance to safeguard downstream communities along the Mulberry Fork river. Further attention and monitoring may be needed to address any potential safety concerns and enhance the dam's resilience in the face of changing climate conditions.

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.
