Summary
1 is a privately owned earth dam located in Fremont, Wyoming, along the Fox Draw tributary of Alkali Creek. Completed in 1977 for irrigation purposes, this dam stands at a height of 33 feet and has a hydraulic height of 28 feet. With a normal storage capacity of 24 acre-feet and a surface area of 3 acres, Bitterroot No. 1 plays a crucial role in sustaining the local ecosystem by providing water for fish and wildlife habitats.
Despite its low hazard potential and fair condition assessment, Bitterroot No. 1 is regulated by the State of Wyoming and undergoes regular inspections to ensure its structural integrity and compliance with safety standards. The dam features an uncontrolled spillway with a width of 124 feet and an outlet gate for water release. The risk assessment for Bitterroot No. 1 indicates a moderate risk level, highlighting the importance of effective risk management measures to mitigate any potential hazards associated with the dam.
Overall, Bitterroot No. 1 serves as a vital water resource infrastructure in Wyoming, contributing to agricultural irrigation and wildlife conservation efforts in the region. Its strategic location and design make it a key component of the local water management system, demonstrating the intersection of water resource management and environmental preservation 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.
