Summary

Built in 1979, this earth dam stands at a height of 10 feet and serves multiple purposes, including fish and wildlife management, irrigation, recreation, and water supply. With a storage capacity of 15,932 acre-feet, the dam helps regulate the flow of the East Fork Smith Creek and provides essential water resources to the surrounding area.

Despite its relatively small size, Stateline Dike B poses a high hazard potential, emphasizing the importance of regular inspections and emergency preparedness. The dam has a hydraulic height of 3 feet and is primarily made of earth and rock materials. While it lacks a spillway, the structure has associated locks and gates for water control. As a critical component of the local water infrastructure, the dam's risk management measures and condition assessment remain crucial for ensuring the safety and longevity of this vital resource.

With its strategic location and significant impact on the ecosystem, Stateline Dike B exemplifies the intersection of water resource management and climate resilience in Utah. As climate change continues to pose challenges to water availability and quality, structures like this dam play a crucial role in safeguarding habitats, supporting agricultural activities, and enhancing recreational opportunities. By prioritizing maintenance, risk assessment, and emergency response planning, stakeholders can mitigate potential threats and ensure the sustainable utilization of this essential water source for current and future generations.

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.
