California aims to improve ability to measure how much water is flowing throughout the state

Sept. 11, 2024
California looks to work with local partners to measure and plan for how much water is flowing throughout the state.

The California Department of Natural Resources (DWR) announced on August 15, 2024, a new partnership opportunity to support the state’s ability to measure stream and river flows through the California Stream Gage Improvement Program (CalSIP) as climate extremes continue to impact the state’s water supply.

As part of the approximately $7 million program, DWR is seeking to partner with public agencies to install, upgrade and/or reactivate existing stream gage stations.

This effort will expand California’s ability to access critical data that can inform important water management decisions during both flood and drought conditions.

A stream gage is a set of instruments installed along a river or stream that measures, records and transmits data on flow, water temperature and dissolved oxygen levels.

Water agencies and the public rely on the essential information these gages provide for multiple purposes including:

  • Planning, forecasting, and warning about floods and drought conditions 
  • Managing and informing reservoir operations
  • Monitoring environmental conditions to protect aquatic habitats
  • Planning for safe and enjoyable recreational activities 
  • Assessing groundwater and surface water interaction
  • Monitoring stream flow impacts due to long-term changes in weather patterns

While there are approximately 1,000 active stream gages across the state sharing information publicly, many watersheds lack vital information on their surface water resources.

Users of this data include emergency responders, water managers, environmental and transportation agencies, universities, utilities, recreators, researchers and Tribes.

DWR is now accepting interest forms which will be reviewed and evaluated monthly to identify eligible projects through December 31, 2024.

The funding will allow approved entities to purchase and install stream gage equipment as well as operate and maintain stations through June 30, 2027.
