Summary
Designed by the USDA NRCS and regulated by the Utah Division of Water Rights, this dam on the SAMARIA LAKE CANAL was completed in 1980 and has a primary purpose of irrigation. With a hydraulic height of 11 feet and a structural height of 14 feet, Peterson Brothers has a storage capacity of 130 acre-feet, providing essential water supply for agricultural activities in the area.
Managed by the Natural Resources Conservation Service, Peterson Brothers is classified as an Earth dam with a significant hazard potential. Although the condition assessment is not rated, regular inspections are conducted, with the last inspection taking place in June 2019. The dam is located in a drainage area that drains to Mallad River, serving as a vital component of the local water infrastructure. With a history of effective water management and a commitment to safety and regulation, Peterson Brothers remains a key asset for water resource enthusiasts and climate advocates in the region.
The dam's location, design, and regulatory oversight ensure its continued functionality and contribution to sustainable water use in Box Elder County. With a focus on irrigation and a storage capacity of 130 acre-feet, Peterson Brothers exemplifies the importance of proper water resource management in supporting agricultural activities and maintaining the ecological balance of the surrounding area. As a privately-owned structure with state and federal regulation, Peterson Brothers stands as a testament to the collaborative effort needed to safeguard water resources and mitigate the impacts of climate change on the local 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.
