Summary

Completed in 1990, this dam serves primarily for water supply purposes, with a storage capacity of 83 acre-feet and a low hazard potential. The dam stands at 18 feet in height and spans 1000 feet in length, impounding water from Tr Latrobe Creek.

Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, Sun Ridge Meadow is subject to state regulation, permitting, inspection, and enforcement to ensure its structural integrity and safety. Despite its small size and low hazard potential, the dam is maintained in satisfactory condition, as assessed in September 2017. In the event of emergencies, such as a breach or flood, the dam may have an emergency action plan in place to mitigate risks and protect downstream communities.

For water resource and climate enthusiasts, Sun Ridge Meadow represents an essential piece of California's water infrastructure, contributing to local water supply and supporting recreational activities in the area. With its scenic location and regulated maintenance, this dam exemplifies the intersection of human engineering and environmental stewardship in managing water resources for the benefit of communities and ecosystems alike.

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.
