Summary

This privately owned structure, designed by ROBERT J. MURDOCK, stands at a height of 57 feet and has a hydraulic height of 56 feet. It serves various purposes including fire protection, stock watering, and maintaining small fish ponds, in addition to its main function of irrigation.

Located in Uinta County, Wyoming, the Broadbent Enlargement of Heber is a crucial water resource for the surrounding area. With a maximum storage capacity of 1084 acre-feet and a normal storage capacity of 894 acre-feet, this dam plays a vital role in providing water for agricultural activities and maintaining water levels for various uses. It spans a length of 475 feet and covers a surface area of 38 acres, with a drainage area of 3.5 square miles.

Despite its high hazard potential, the dam has been inspected regularly, with the last inspection conducted in May 2021. The structure has three outlet gates and an uncontrolled spillway, ensuring proper water management and safety measures. With a moderate risk assessment rating, the Broadbent Enlargement of Heber continues to be a key infrastructure for water resource management in the region, showcasing the importance of sustainable water practices in the face of changing climates and water availability.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
