Summary

Constructed in 1962, this earth dam stands at a height of 51 feet and has a storage capacity of 376 acre-feet. Situated along the Tr Franz Creek, the dam plays a crucial role in providing water to the surrounding area, supporting agricultural activities and ensuring water supply for the community.

Managed by the Natural Resources Conservation Service, Kellogg Ballpark Dam is regulated by the California Department of Water Resources, ensuring regular inspections and enforcement of safety measures. Despite its high hazard potential, the dam's condition assessment remains satisfactory as of September 2017. With a history of meeting safety guidelines and a recent inspection in August 2020, the dam continues to play a crucial role in water resource management in Sonoma County.

Recognized for its important role in water supply infrastructure, Kellogg Ballpark Dam serves as a key component in the region's water management strategy. As climate change continues to impact water resources, the dam's ability to store and regulate water flow becomes increasingly important. With its long-standing history and critical function in supporting agriculture in the area, the dam remains a significant asset in the face of evolving climate challenges and water resource management needs.

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.
