European catchments and Rivers network system (ECRINS), lakes and reservoirs - version 1, Jun. 2012

The database comprises the following tables: feature class C_Lak with all information related to all still waterbodies which area is more than the Corine Land cover threshold, plus those identified because a reservoir or any other relevant source. This table is completed by the centroids of lakes, V_lak_Centro. The complex relationships between lakes and river segments are documented by table lakInOut where the inlet and the outlet(s) segments are reported. Complementary tables, needed by the water accounts, v_lakperadmin et v_linterfec respectively document the lake to administrative entities with shared area and same with FECs. Being in relation with the other components of Ecrins, lakes are versioned with respect to catchments and rivers and with their update as well. Lake naming comes from fours sources: ERM, Eldred2, Art 13 reporting and Wikipedia. Hydrographical information (volume, Zaverage, Zmax) and is permanently updated from three source: Eldred2, the dams database, and Wikipedia. In version 1.0, the history of lakes is not documented. Most natural lakes have a time span much before and beyond the expected duration of Ecrins. Artificial lakes, related to dams have their history documented with the dam and some natural lakes are intermittent. This last category is not documented. Since lower limit for lake inclusion is 25 ha, all “main lakes” under the WFD acceptation are present (except if missed for any reason, the most likely being creation of an artificial reservoir not present in the latest update).

Main source is Corine Land cover 2006, checked against ERM lakes layer for identifying relevance of Corine Land cover classification. Secondary sources are Eldred2 (EEA dams database) and WFD Art 13 deliveries. For example, a large dams mentioned in Eldred with a lake of sufficient area is verified against the lake layer and eventual correction on Corine Land cover is carried out; this was often the case for narrow and long reservoirs on rivers that are frequently clustered, forgotten or ill-classified in Corine Land cover. The presence of lake in different sources is mentioned in the C_lak table and if possible the ID of the source element reported as well as the ID of the matched ERM lake, hence making a bridge between the Ecrins (operational data set) and the user of ERM (geographical data set). Lake naming comes pro-parte from ERM, when a match is found and verified against other sources, from Art 13 reporting and from Wikipedia. Lakes matched to Wikipedia entries are as well flagged.
