Summary
2 is a privately owned earth dam located on Texaco Draw in Niobrara, Wyoming. Built in 1962, this dam serves multiple purposes including fire protection, stock watering, and as a small fish pond. The dam stands at 23 feet high with a hydraulic height of 18 feet and a length of 1400 feet. It has a storage capacity of 199 acre-feet and covers a surface area of 16 acres.
Despite being classified as having a low hazard potential, Provost No. 2 is regularly inspected by state regulators and meets all permitting and enforcement requirements. The dam's condition is assessed as fair, with the last inspection conducted in April 2020. It has an uncontrolled spillway with a width of 260 feet, and there are no outlet gates associated with the structure. The risk assessment for this dam is moderate, indicating the need for ongoing monitoring and risk management measures.
Overall, Provost No. 2 plays a crucial role in water resource management in the region, providing important services for fire protection and agricultural use. Its location in a rural area highlights the importance of maintaining and monitoring dams to ensure public safety and environmental protection. As a key feature on Texaco Draw, this dam serves as a significant infrastructure asset for the community of Edgemont S D and surrounding areas, demonstrating the vital role that water resources play in sustaining both ecosystems and human activities 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.
