Summary

Ogden. The wetlands are regulated by the State of Wyoming and serve as a habitat for various species in the area. Completed in 1989, the earth dam stands at a height of 12 feet and has a hydraulic height of 6 feet, with a total structural height of 15 feet.

Covering a surface area of 24 acres with a drainage area of 3.9 square miles, the wetlands have a normal storage capacity of 105.26 acre-feet. The dam, primarily made of earth with stone core types and a soil foundation, features an uncontrolled spillway with a width of 20 feet. With a low hazard potential and fair condition assessment, the wetlands provide a valuable ecosystem for wildlife while also serving as a resource for water management and conservation efforts in the region.

Managed by the Sacramento District of the US Army Corps of Engineers, Soda Lake Wetlands is an essential component in the local water infrastructure, offering recreational and environmental benefits to the community. With its moderate risk assessment and regular state inspections, the wetlands continue to play a crucial role in maintaining water quality and supporting biodiversity in the area.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
