Summary

Built in 1916, this earth dam stands at 40 feet high and spans 320 feet in length, with a storage capacity of 380 acre-feet. The lake is fed by Lesnini Creek and serves as a crucial water source for the surrounding area, covering a surface area of 44 acres and draining an area of 1.36 square miles.

Managed by the California Department of Water Resources (DWR) for safety and regulatory oversight, Rodden Lake boasts a low hazard potential and a satisfactory condition assessment. The dam is inspected annually, with the last assessment conducted in January 2021. It is reassuring to know that the state of California takes its responsibility for ensuring the safety and functionality of this essential water resource seriously, with permitting, inspection, and enforcement all in place.

With its rich history, vital purpose, and meticulous maintenance, Rodden Lake stands as a testament to the intersection of water resource management and climate resilience. From powering hydroelectric generators to supporting local agriculture through irrigation, this lake plays a vital role in the water infrastructure of Stanislaus County. For water resource and climate enthusiasts, Rodden Lake is a prime example of how strategic planning and regulatory oversight can ensure sustainable water management practices for generations to come.

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.
