Please note: In many cases, the station position in our database is accurate
to only one minute. Thus, the tide gauge may not appear to be on the coast.

All data up to and including 1998 has been received from the UHSLC so the supplying authority has been changed to UHSLC. From the UH levelling sheet the RLR diagram was produced using the 1983 levelling information. Primary benchmark UH 1 12.791ft(3.899m) above the datum. The value remained the same for the 1986 levelling but became unstable from the 1988 levelling onwards.
