Summary

Constructed in 1979 by Nielsen, Maxwell & Wangsgard, this earth dam stands at a structural height of 20 feet and has a hydraulic height of 18 feet. With a normal storage capacity of 17 acre-feet, this reservoir serves primarily for irrigation purposes in the region.

Regulated by the Utah Division of Water Rights, this reservoir has a high hazard potential but is currently assessed to be in fair condition. The last inspection was conducted in July 2020, with inspection frequency set at once per year. The reservoir is situated in a strategic location to support agricultural activities in the area and plays a crucial role in water resource management in Davis County, Utah.

Despite its small storage capacity and limited drainage area, Farmington Irrigation - Reservoir C plays a vital role in ensuring water availability for farming operations in the region. As a key component of the local irrigation infrastructure, this reservoir underscores the importance of efficient water management in the face of changing climate conditions. With its earth dam structure and state-regulated status, this reservoir exemplifies the resilience and adaptability required to sustain water resources in a changing climate landscape.

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.
