Summary
This lagoon serves a primary purpose of waste water management and has a normal storage capacity of 157 acre-feet. The dam stands at a height of 18 feet and stretches 2750 feet in length, with a surface area of 9 acres.
With a low hazard potential and satisfactory condition assessment as of June 2019, Wheatland Waste Water Lagoon 2 has been inspected regularly every five years. The dam overlooks Rock Creek and is under the jurisdiction of the Wyoming State Engineer's Office. Despite not having an Emergency Action Plan (EAP) in place, the lagoon has been deemed to meet regulatory guidelines and presents a minimal risk to surrounding areas.
Overall, Wheatland Waste Water Lagoon 2 plays a crucial role in managing waste water in the region while adhering to state regulations and inspection requirements. As a publicly-owned utility structure, it stands as a testament to responsible water resource management and environmental stewardship 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.
