Current California Streamflow Conditions
The colored dots on this map depict streamflow conditions as a percentile
, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record
are used. The gray circles
indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.
