Summary
Designed by JOHN W. DONNELL and completed in 1992, this Earth-type dam plays a vital role in regulating the Big Horn River's water flow. With a structural height of 15 feet and a capacity of 62 acre-feet, the facility serves as a key point of water storage and treatment for the region.
Operated by the local government, the Worland Wastewater Treatment facility has been deemed to have a low hazard potential and fair condition assessment. While it is state-regulated and undergoing regular inspections, the facility's risk assessment identifies a high level of risk, emphasizing the importance of effective risk management measures. With its uncontrolled outlet gates and proximity to the river, the facility plays a crucial role in ensuring water quality and environmental protection in Washakie County.
Despite its low hazard potential, the facility's high risk rating underscores the need for continued vigilance in maintaining its structural integrity and operational efficiency. As a critical piece of infrastructure in the region, the Worland Wastewater Treatment (Cell 4) facility stands as a testament to the importance of water resource management and climate resilience in the face of evolving environmental challenges.

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.
