► Mesoscale sampling spread out in time allows detection of environmental patterns. ► ArcGIS analysis of river catchment attributes shows spatial structure in Ireland. ► Lake trophic status relates with land cover typology of river catchment. ► Phytoplankton community structure relates to seasonality and meteorology.
