Ullapool 1978 charts badly trimmed , data unreliable1979 Sept-Oct results suspect 1980 very bad damp and badly maintained. 1965 values based on high and low waters.

A Lea stilling well gauge was installed in April 1963, replaced by a Munro in the same well in 1981. Since May 1987 the gauge has been an "A Class" bubbler system.

There was an electrical fault at site from the end of September through to November.TGI were at site 3.10.14 for General maintenance,change the compressor and to rectify water/damp damage and refurbishment.

A value of MTL-MSL=-73 mm has been derived using the GESLA2 (high-frequency tide gauge) dataset using harmonic constituents. As the correction is only applied to RLR data and the data from 1965 is metric, it is not used in the data set. Should this period become metric in future, however, it would be used. The 001 flag has been set only because this correction is highly uncertain.
