Data are given on the morphometry, substrata of the littoral zone, water quality, vegetation and benthic macroinvertebrate assemblages of Oak Mere, a lowland English Lake, in 1994 and 1996. In 1994, vegetation was confined to a sparse marginal zone containing very few individuals of macroinvertebrates with a community structure characterised by high diversity and maximum equitability. By 1996, this marginal zone had increased in area and a new submerged vegetation zone had developed. The new and substantial macroinvertebrate assemblages of these two 1996 zones were closely similar in species composition, species richness, diversity and equitability. In both sampling years the macroinvertebrate assemblages of a niche provided by the undersides of stones remained similar in all respects. The development of marginal and submerged vegetation zones, providing niches for macroinvertebrates, is attributed to a stable water level between the two sampling years.
