Do you have the flow rate at a specific location on a creek?

The Flood Control District has over 2,000 data points where the flow rates have been calculated. Most of these are the “design” flow rates based on General Plan build out2. Depending on the watershed size, the flow rate could be for the 10-year, 25-year, 50-year or 100-year flood. For information on the flow rates that the Flood Control District has for these data points call the
County Public Works Department, Flood Control Division at (925) 313-2000 or email your request.
