This document is applicable to standing waters with surface areas greater than 1 ha (0,01 km2) and maximum depths (at mean water level) greater than 1 m. All types of permanent standing waters, including natural and artificial (thus including reservoirs), fresh water and brackish, except for those systems regularly connect to the sea, are included in this European Standard, though canals are excluded. Based on these criteria it can be estimated that there are at least 500000 natural lakes across Europe, most of which are located in the glaciarised landscapes in northern and western provinces and in Scandinavia. Lakeland districts also occur locally in areas such as the Danubian and Hungarian plains and around the Alps. Elsewhere naturally occurring lakes are relatively sparse and in such areas reservoirs are the most common type of standing water. This European Standard a) defines the key term of hydromorphology and related terms relating to the physical characteristics of lakes and their hydrological regimes; b) details essential features and processes of lakes that should be characterised as part of a hydromorphological survey and thus to determine the hydromorphological condition of a lake; c) identifies and defines the key pressures impacting on European lakes; d) provides guidance on strategies for collecting hydromorphological data depending on resources available and the anticipated use of the assessment. A hierarchy of approaches is recognised spanning from the "overview method" utilising existing databases, maps and remote sensing data through to recognised field-based survey techniques such as Lake Habitat Survey (LHS); e) offers assistance in interpreting the data; f) establishes guidance on data quality assurance issues. This European Standard is designed to support environmental and conservation agencies meet the monitoring requirements of the WFD (Article 8, Annex II and Annex V).
