Summary
The earth dam stands at 24 feet high with a hydraulic height of 19 feet and a length of 320 feet, creating a storage capacity of 70 acre-feet for Willow Creek. Despite having a low hazard potential, the dam is state-regulated and inspected regularly to ensure its safety and functionality for the surrounding area.
This dam, with a surface area of 6 acres, plays a crucial role in managing water resources in the region, especially during fire emergencies and for supporting livestock and aquatic life. It is situated in proximity to I-90 and managed by private owners, under the oversight of the Wyoming State Engineer's Office. With a moderate risk assessment score of 3, efforts are in place to continually assess the condition of the dam and implement necessary risk management measures to address any potential safety concerns.
The dam at Shearing Pen serves as a vital infrastructure for the local community, contributing to water security and climate resilience in the area. Its strategic location and purpose highlight the importance of proper maintenance and regulatory oversight to ensure the continued reliability and safety of the structure for both present and future needs.

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.
