Summary
Built in 1945, this earth dam stands at a height of 18 feet, with a hydraulic height of 13 feet and a length of 648 feet. The reservoir has a storage capacity of 270 acre-feet and serves a drainage area of 36.7 square miles, making it a vital resource for water supply in the region.
Managed by the Utah Division of Water Rights, Hogback is regulated, permitted, inspected, and enforced by state authorities to ensure its safe operation and compliance with water resource regulations. The dam has a low hazard potential and is categorized as "Not Rated" in terms of condition assessment. Although the last inspection took place in May 2017 with a frequency of every 5 years, no emergency action plan (EAP) has been prepared, and there is limited information available on risk assessment and management measures for the structure.
Despite its modest size and limited risk profile, Hogback plays a crucial role in providing essential water services for fire protection, livestock, and recreational purposes in the area. As climate change continues to impact water resources, structures like Hogback will be increasingly important in ensuring the sustainable management and utilization of water in a changing environment.

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.
