Summary
With a height of 33 feet and a storage capacity of 1,100 acre-feet, this dam plays a crucial role in protecting the surrounding area from potential flooding events. The dam is under state jurisdiction and is regulated, permitted, inspected, and enforced by the California Department of Water Resources, Safety of Dams division, ensuring its structural integrity and safety.
This high-hazard dam has a satisfactory condition assessment as of September 2017 and is subject to regular inspections, with the last one conducted in February 2021. Redbank's hazard potential is classified as high, highlighting the importance of its maintenance and monitoring. Despite not having associated structures, Redbank serves a vital purpose in flood risk reduction within the region, covering a drainage area of 15.56 square miles and providing a surface area of 195 acres for water storage. Enthusiasts interested in water resources and climate will find Redbank to be an essential infrastructure contributing to the protection and management of water resources in Fresno.
Redbank's location along the Redbank Creek and its proximity to Fresno make it a crucial asset in water management and flood control efforts in California. With its significant storage capacity and role in reducing flood risks, Redbank stands as a testament to the state's commitment to water resource management and infrastructure development. Climate and water resource enthusiasts can appreciate the engineering feat of this dam, which continues to play a vital role in safeguarding the local community against potential flooding events, demonstrating the importance of sustainable water management practices in the face of a changing climate.

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.
