The LOIS Rivers Data Centre assembled a large water quality database from many sources and suppliers. As there were few standards for water quality data LOIS developed its own covering terminology, units and coding. LOIS has also highlighted the fact that many of the existing lists of algae, macrophytes and invertebrates and other species were out of date and needed revision.

Remedying this situation was beyond the resources available within LOIS, but the Rivers Data centre was able to make two major contributions in the form of:

The LOIS Chemical Determinand Dictionary
A Coded List of Freshwater Algae of the British Isles 1998 Version
The latest CEH Chemical Determinand Dictionary
A Coded List of Freshwater Algae of the British Isles 2003 Version
