reference is by electric drop tape.

REMARKS.--The primary record is hourly satellite data and mean daily gage heights from the chart. Daily
maximum and minimum stages for the satellite record checked to within ± 0.02 with the chart. Where
DCP data was missing, data was entered hourly from the chart. The clock stopped a few times during
the season, but the satellite data was complete so no data was lost during these times. The record
is good. Station maintained and record developed by M.L. Cunning.
