Summary
The dam, with a height of 21 feet and a hydraulic height of 16 feet, serves multiple purposes including fire protection, stock watering, and maintaining a small fish pond. It has a storage capacity of 93 acre-feet and a surface area of 9 acres.
Despite its low hazard potential, Natural Bridge is currently in poor condition as of the last inspection in June 2017. The dam has a moderate risk assessment rating of 3, indicating the need for risk management measures to ensure its continued safety and functionality. The dam is regulated by the Wyoming State Engineer's Office and undergoes regular inspections, permitting, and enforcement to maintain compliance with state regulations.
Located in a beautiful natural setting, Natural Bridge offers a serene water resource for both local wildlife and recreational enthusiasts. With its historical significance and important role in water management, the dam serves as a vital infrastructure for the surrounding area while also highlighting the intersection of water resources and climate impacts.

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.
