Summary

Managed by the Public Utility, this reservoir serves as a critical water supply for irrigation, tailings, and general water needs in the region. Built in 1945, this Arch type dam stands at an impressive height of 203 feet, with a maximum storage capacity of 25,400 acre-feet spread across its 454-acre surface area.

Situated along the Sweetwater River, Lake Loveland plays a vital role in the local water management infrastructure, with state agencies ensuring its regulatory compliance and safety through regular inspections and enforcement measures. Despite its high hazard potential, the dam is deemed to be in satisfactory condition, as assessed in September 2017. This reservoir not only provides essential water resources but also offers a picturesque setting for climate and water resource enthusiasts to appreciate the intersection of engineering marvels and natural beauty.

As a key component of the water supply network in San Diego County, Lake Loveland's historical significance and ongoing operational importance make it a focal point for understanding the complex interactions between human intervention and environmental sustainability. With its strategic location, impressive structural design, and critical role in water management, this reservoir stands as a testament to the intricate balance between harnessing natural resources and ensuring their responsible management for 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.
