Summary

Built in 1898, this Earth dam stands at a structural height of 11.5 feet with a hydraulic height of 4.5 feet. Its primary purpose is for recreation, offering a storage capacity of 400 acre-feet and a normal storage of 90 acre-feet. The dam has a low hazard potential and has not been rated for its current condition.

Managed by the Utah Division of Water Rights, Smiths is subject to state regulation, permitting, inspection, and enforcement. Although it has not been modified in recent years, the dam underwent its last inspection in July 2011 with a scheduled inspection frequency of 5 years. The dam is located within the Omaha District of the US Army Corps of Engineers jurisdiction and falls under the representation of Congressman John R. Curtis.

With its historical significance dating back over a century, Smiths dam serves as a focal point for recreational activities in the area while also contributing to the local water resource management efforts. Its low hazard potential and steady storage capacity make it a valuable asset for both the community and the environment, highlighting the importance of maintaining and monitoring such infrastructure for sustainable water resource management in the face of changing climate conditions.

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.
