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.
