Summary

Built in 1967 by the USDA NRCS, this earth dam stands at a hydraulic height of 21 feet and a structural height of 27 feet, with a length of 310 feet. It serves the primary purpose of irrigation, with a storage capacity of 100 acre-feet and a drainage area of 4 square miles, making it a crucial water resource for the area.

Managed by the Utah Division of Water Rights, Anderson Doty is regulated, permitted, inspected, and enforced upon to ensure its safety and functionality. The dam has a low hazard potential and has not been rated for condition assessment yet. Despite being non-federal, it meets regulatory guidelines and is subject to regular inspections every 5 years. The dam is a key component in the local water infrastructure, contributing to the management and distribution of water resources in the region.

The dam is situated on a tributary to Cub River and falls under the jurisdiction of the state of Utah. Although it has not undergone modifications or has an emergency action plan in place, Anderson Doty continues to play a vital role in irrigation and water management in the area. With its historical significance and ongoing importance, this dam serves as a focal point for water resource and climate enthusiasts interested in the sustainable use of water in the region.

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.
