SUMMARY. 1. Constrained cluster analysis of thirty‐five surface sediment diatom assemblages shows that Lough Erne, a complex multi‐basin lake in Northern Ireland, can be sub‐divided into four main zones. 2. All areas of the lake system have planktonic diatoms typical of eutrophic lakes but the lack of small Stephanodiscus species in zone 4 suggests that this area of the system is least productive. 3. Surface sediment diatom assemblages can be used to assess spatial variations in complex lake systems and can thereby be used as a guide to the choice of sites for water quality monitoring and sediment coring.
