Summary
Built in 1959, this structure stands at a height of 32 feet and has a storage capacity of 96 acre-feet. The dam spans 415 feet in length and covers a surface area of 7 acres. Despite being classified as a low hazard potential, the condition assessment in 2018 rated it as fair, with a moderate risk level of 3.
Owned by a private entity, Cadiz Stock is regulated by the Wyoming State Engineer's Office and is subject to state permitting, inspection, and enforcement. Situated along the Leiter or Cadiz Draw stream, this dam serves the local community by providing vital water resources for firefighting and livestock needs. Although it has not undergone any modifications in recent years, regular inspections ensure its structural integrity and safety for surrounding residents.
Managed by the Omaha District of the US Army Corps of Engineers, Cadiz Stock is a key component of the water infrastructure in Sheridan, Wyoming. With Congresswoman Liz Cheney representing the area, this dam plays a crucial role in maintaining water resources for agricultural and environmental purposes. As a focal point for climate and water resource enthusiasts, Cadiz Stock embodies the delicate balance between human necessity and environmental stewardship in the face of changing climate patterns.

Dam Data Reference
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.
