Summary
4050sr, serves multiple purposes including fire protection, stock watering, and as a small fish pond. Built in 1960 by designer Adam Bedard, this private earth dam stands at 32 feet tall with a length of 489 feet, providing a storage capacity of 52 acre-feet for the SE 29 Fork river or stream. Despite its low hazard potential and fair condition assessment, the dam is regulated, inspected, and enforced by the Wyoming State Engineer's Office and Department of Environmental Quality.
With a surface area of 4.04 acres and a drainage area of 0.18 square miles, the T55nr76w29nwse dam has a maximum discharge rate of 212 cubic feet per second through an uncontrolled spillway. The dam's outlet consists of a single valve, and it is located on HWY 14/16 in Congressional District 00, Wyoming, represented by Liz Cheney (R). The dam's risk assessment is moderate, and it undergoes inspections every 5 years, with the last assessment conducted in August 2018, indicating it meets state regulatory guidelines.
Water resource and climate enthusiasts will find the T55nr76w29nwse dam an intriguing structure that not only provides essential services for fire protection and livestock but also supports local fish and wildlife habitat. Its location within the scenic landscape of Sheridan, Wyoming, and its role in water management make it a vital piece of infrastructure for maintaining a sustainable environment in the region. Despite its age, the dam continues to operate effectively, demonstrating the importance of proper maintenance and regulation in ensuring the safety and reliability of water resource systems.

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.
