Summary
Completed in 1994, this Earth-type dam stands at a structural height of 9 feet and stretches 100 feet in length, providing a storage capacity of 75 acre-feet. Despite its undetermined hazard potential and not-rated condition assessment, the dam has not undergone recent inspections, and its emergency action plan status remains unclear.
The dam's primary purpose is classified as "Other," and it operates within the jurisdiction of the Utah state regulatory agency. While specific details on associated structures, spillway type, and outlet gates are not provided, the dam's location at 21,10N~3W SL suggests its significance in the water resource management of the region. The absence of information on risk assessment, emergency preparedness, and contact updates raises concerns about the dam's resilience and management measures in case of potential hazards or emergencies.
With its proximity to the Omaha District and representation by Congressman Rob Bishop (R), Hansen, Collin 94-29-72md holds strategic importance in the water infrastructure of Utah. However, the lack of recent inspections, condition assessments, and updated emergency protocols highlight the need for improved monitoring and risk management strategies to ensure the safety and longevity of this essential water resource structure. Enthusiasts of water resources and climate resilience may find value in exploring the potential implications and challenges associated with the maintenance and regulation of this dam.

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.
