Levels are metres above each gauge's own zero (tidal stations: metres above sea level, AOD), so a number at one station cannot be compared with another. The trend compares the latest reading with one from at least 45 minutes earlier.

What high, normal and low mean

High Above its normal range at that station.
Normal Within its normal range at that station.
Low Below its normal range at that station.

Flood warnings are separate

A river above its normal range is often not flooding anything. Flood warnings come from the Environment Agency in England. Floodline is 0345 988 1188, 24 hours a day. This site does not issue warnings.

Questions

Is the River Thames high right now?

No. None of the 56 stations on the River Thames with a recent reading and a normal range is above that range: 46 normal, 10 low (checked 7:47 pm UK time, 19 October).

Where is the level of the River Thames measured?

The Environment Agency measures the River Thames at 65 stations, including Abingdon Lock, Bell Weir, Benson Lock, Boulters Lock and Boveney Lock. The stations are grouped by catchment, because more than one river can carry this name.

What is the normal level of the River Thames?

It depends on the station, because each gauge has its own zero. At Abingdon Lock the normal range is -0.25 m to 0.20 m, and the highest level on record there is 0.58 m (9 January 2014). The other stations are listed on this page with their own ranges.

Does a high river level mean there is a flood warning?

No. A level above the normal range is often not flooding anything. Flood warnings and flood alerts are issued separately by the Environment Agency in England, Natural Resources Wales and SEPA in Scotland, and this site lists England's on its flood warnings pages. Floodline is 0345 988 1188, 24 hours a day.
