Instream Flow Administrative Calls
The CWCB monitors streamflow to ensure decreed instream flow (ISF) water rights are protected. If streamflow drops lower than the amount decreed to an ISF water right, and that right is in priority, staff may place an administrative call for water. The following links provide information about specific calls for water.
