Summary
Designed by Mickey M. Yamashiro and completed in 1978, this Earth dam structure on Sugar Creek, a tributary of the North Platte River, serves as a vital component for managing wastewater in the area. With a dam height of 15 feet and a storage capacity of 59 acre-feet, the plant covers a surface area of 140 acres and plays a significant role in water resource management.
Despite its fair condition assessment as of 2017, the Rawlins Wastewater Treatment Plant poses a significant hazard potential due to its location and purpose. The dam is inspected every 5 years, with the last inspection conducted in July 2017. Its risk assessment is classified as high, emphasizing the importance of regular monitoring and maintenance to ensure its structural integrity and prevent any potential risks to the surrounding community. With no spillway and a low maximum discharge rate, it is crucial to stay vigilant in managing this essential water resource infrastructure.
As water resource and climate enthusiasts, understanding the significance of the Rawlins Wastewater Treatment Plant (A 1) is crucial in appreciating the complexities of water management in the region. With its strategic location and role in maintaining water quality and quantity in the area, this facility stands as a testament to the ongoing efforts to safeguard our natural resources. By staying informed and engaged in the maintenance and regulation of such structures, we can contribute to a sustainable future for water resources and climate resilience in Wyoming.

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.
