2005 data flagged suspect. Data looks way out - authority contacted to confirm datum etc. of data.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 08-Sep-2008
There is what appears to be a datum shift from 2003 onwards. Following levelling carried out at site the Authority has said that the offset for the data is 0.583m. When this was added to the relevant data the plot appears to be acceptable. The previous flags were removed from the individual data points as the station itself is flagged. However, the data must still be used with caution.

While researching datum and benchmark information prior to uploading the RLR diagram onto the website it was noted that the bench mark from 1987 onwards changes from BM PJ2 4.41m above the gauge datum to BM 1 5.826m above the datum. The datum remains the same.
