Last Updated:



The primary focus is on enhancing flow in streams that support anadromous fish; support special status, threatened, endangered, or at-risk species; and/or provide resilience to climate change. Enhanced stream flow is defined as a change in the amount, timing, and/or quality of the water flowing down a stream, or a portion of a stream, to benefit fish and wildlife.


WCB anticipates awarding up to $15 million in grants selected through this PSN, and funds must be expended by March 31, 2027.

The priorities of the 2021 Stream Flow Enhancement Program solicitation will be to support projects that:

• Directly result in meaningful increases in the availability and/or quality of water in streams such as through the acquisition or long term dedication of water rights.

• Are located in southern California, though projects located in other regions will also be accepted.

• Evaluate stream flow conditions and stream responses to previous Stream Flow Enhancement Program projects.

• Are consistent with the objectives and actions outlined in the CWAP

Proposals must demonstrate that the proposed project will enhance stream flow at a time and location necessary to provide fisheries or ecosystem benefits (i.e., help alleviate a limiting factor). Proposals must also clearly identify the target stream(s), stream reaches, and watershed(s) in which proposal activities will occur as well as the reaches where project benefits will be realized.

Please see the announcement on WCB’s website for the full PSN document, application form, and more information.
