In an effort to update existing information on the site condition of these lakes and provide additional information on other Welsh lakes in SACs, former Countryside Council for Wales (CCW) commissioned surveys on a further 19 lake sites in 2004. This dataset brings together data collected in 2003 and 2004 from 28 Welsh lakes in 11 SACs. Limnological data collected for the purpose of site condition assessment and to provide a series of lake data reports on each of the 11 specified SACs.

The plant surveys consisted of a strandline survey, emergent and marginal survey, shoreline wader survey and boat survey using either a bathyscope or a double-headed rake. Estimates of species abundance converted to a DAFOR scale. Physico-Chemical Survey- Dissolved oxygen and temperature profiles and Secchi disk depth were recorded. Chlorophyll a samples analysed. Chemical determinands analysed. Acid neutralising capacity (ANC) calculated. Bathymetric Surveys and Catchment Mapping produced using a boat mounted Lowrance LMS240, a combined GPS receiver and echo sounder. Diatom Analysis- A sediment core was taken in the summer of 2004 from the deepest part of each lake using a Glew gravity core. Data collected in an effort to update existing information on the site condition of these lakes and to provide additional information on other Welsh lakes in SACs.
