Summary
Little Soda, located in Weston, Wyoming, is a private irrigation dam constructed in 1909 on Box Elder or Little Soda Creek. With a height of 16 feet and a storage capacity of 148 acre-feet, this earth dam serves multiple purposes including fire protection, stock watering, and small fish pond support. Despite its low hazard potential, the dam's condition assessment is rated as poor, emphasizing the need for maintenance and potential upgrades to ensure its long-term integrity.
The dam's spillway is uncontrolled with a width of 30 feet, and it is equipped with a single valve outlet gate for water release. Although the dam has not undergone significant modifications over the years, regular inspections are conducted every 5 years to assess its structural stability and safety. With a moderate risk assessment rating of 3, it is crucial for authorities to implement risk management measures to mitigate any potential hazards associated with the dam's deteriorating condition.
Enl. Little Soda's location in a rural area underscores its importance for local water resource management and agricultural activities. As water resource and climate enthusiasts, it is essential to monitor and support initiatives that ensure the sustainability and safety of dams like Enl. Little Soda to safeguard water availability and ecosystems in the region.

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.
