• The California Department of Water Resources (DWR) has launched the California Stream Gage Improvement Program (CalSIP).
• CalSIP will partner with public agencies to install, upgrade, and/or reactivate stream gage stations throughout California.
• The program aims to enhance the state’s ability to measure stream and river flows, improving water management decisions and flood and drought preparedness.

August 16, 2024 — The California Department of Water Resources (DWR) announced yesterday the California Stream Gage Improvement Program (CalSIP) launch. This initiative is intended to enhance the state’s ability to measure stream and river flows by partnering with public agencies to install, upgrade, and reactivate stream gage stations.

DWR Director Karla Nemeth emphasized the importance of this program, stating, “California can’t manage what we don’t measure. Expanding our network of gages in rivers and streams helps us all make better decisions about managing our precious water supply while protecting vulnerable communities from flooding and drought.”

Stream gages provide essential data on flow, water temperature, and dissolved oxygen levels. This information is crucial for various purposes, including flood and drought planning, reservoir operations, environmental monitoring, recreational planning, and assessing groundwater and surface water interactions.

The CalSIP program, with approximately $7 million in funding, will enable approved entities to purchase and install stream gage equipment and operate and maintain stations through June 30, 2027. The real-time stream data transmitted from these gages will be publicly shared on the California Data Exchange Center website.  (The map can be viewed here.)

Teresa Connor, CalSIP program manager with DWR, highlighted the significance of filling gaps in the stream gage network to protect life and property, improve water supply forecasting, and enhance recreational opportunities.

DWR is accepting interest forms, which will be evaluated monthly to identify eligible projects through December 31, 2024. Applicants are encouraged to apply as soon as possible. Additional information about the program and how to apply can be found on the CalSIP webpage.

This initiative is part of a broader effort authorized by Senate Bill 19 to address gaging information gaps in collaboration with other state agencies. It reflects California’s commitment to proactive water management and preparedness in the face of climate extremes.
