Waterbase-Lakes: Stations

The Stations table contains the physical characteristics of the Eionet-Water lake monitoring stations. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Stations with their respective Quality and Pressures data.

Table definition
LakeResidenceTime Average water residence time expressed as years average lake residence time in years. Calculated as volume/annual flow. float(8) 0
LakeVolume Lake volume volume of water in lake in million m3. float(8) 0
LakeArea Lake area surface area of lake in km2. float(8) 0
Latitude Latitude (Y) international geographical co-ordinates in decimal degrees format. Latitude provided using the common geodetic datum ETS89 (rivers, lakes, groundwater, water quantity) or WGS84 (TCM). Where TCM stations represent a broader area, the central location of the area is provided. float(8) 0
LakeMaxDepth Lake maximum depth maximum depth of the lake in m. float(8) 0
LakeMeanDepth Lake mean depth mean depth of the lake in m. float(8) 0
CatchmentArea Catchment area catchment area upstream of the station, in km2. For lakes, the catchment area upstream of the lake is shown. If more than one station exists in the lake, the catchment area value should be the same for all stations. float(8) 0
Altitude Altitude altitude of station in m above sea level. For lakes, the altitude of the lake is provided. float(8) 0
Longitude Longitude (X) international geographical co-ordinates in decimal degrees format. Longitude provided using the common geodetic datum ETS89 (rivers, lakes, groundwater, water quantity) or WGS84 (TCM). Negative values used for co-ordinates west of the Greenwich Meridian (0 degrees). Where TCM stations represent a broader area, the central location of the area is provided. float(8) 0
ImpactStation Impact station impact station type, located within the zone where initial mixing of discharges takes place with receiving waters. Concentrations may be worst-case. Impact stations may be used to assess the compliance of discharges with standards established for hazardous substances and may be included in operational monitoring programmes as required by the WFD. Data are not required from investigative monitoring stations. River and lake stations can be of more than one type. 1=yes, 0=no. int(4) 0
Reservoir Reservoir reservoir or natural lake: 1=yes (reservoir), 0=no (lake). int(4) 0
LargestLake Largest lake largest, most important station type, including the nationally most important or well known rivers or lakes. Some stations are likely to be monitored for the EU Exchange of Information Decision. River and lake stations can be of more than one type. 1=yes, 0=no. int(4) 0
ReferenceLake Reference lake reference station type, found in catchments or associated River Basin Districts with little or no human activity, natural landscape higher than 90%, and minimally impacted by inflow from adjacent coastal or marine waters. Concentrations of nutrients or hazardous substances occurring naturally would give an indication of background levels. For volatile sunthetic substances, data from these stations might be used to assess the significance of atmospheric deposition. River and lake stations can be of more than one type. 1=yes, 0=no. int(4) 0
RepresentativeLake Representative lake representative station type, reflecting the general quality of rivers, lakes, transitional or coastal water bodies or marine water areas. Quality influenced by diffuse and/or point sources of pollution from upstream activities. Pollutants from point sources would be fully mixed and diluted within the ambient water flow/volume. Stations may be part of national networks monitoring nutrients, organic matter and hazardous substances. They may be included in surveillance and/or operational monitoring programmes as required by the WFD. River and lake stations can be of more than one type. 1=yes, 0=no. int(4) 0
NationalStationID National station ID identifier of the river or lake monitoring stations, the water quantity station, the transitional, coastal or marine flux or montoring station, all unique at the national level. A transitional, coastal or marine station should be a geographically fixed location, an area in which actual sampling locations vary from survey to survey or an area within a defined salinity range within which samples have been taken. Each station is referred to be its single, central location. For transitional, coastal or marine flux stations, the NationalStationID should be the same as that provided for the river flux station. nvarchar(255) 0
Remarks Remarks remarks, comments or explanatory notes. nvarchar(255) 0
Country Country name official short name in English. ISO 3166-1. nvarchar(255) 0
WaterbaseID Waterbase ID internally produced, unique identifier used to represent the monitoring station for rivers, lakes, transitional, coastal and marine waters, and water quantity, in the format CountryCode_WaterDataSet_NationalStationID (e.g. AT_RV_001), or the groundwater body, in the format CountryCode_WaterDataSet_EWN-Code (e.g. AT_GW_AT001). nvarchar(255) -1
WaterbaseName Waterbase name national name of station or groundwater body. nvarchar(255) 0
Region Region national region in which water body is located. nvarchar(255) 0
CountryCode Country code abbreviation of EEA Member or Collaborating country. ISO 3166-alpha-2 code elements. varchar(2) 0
DataSource Data source source of data: Eionet-Water, ICES. varchar(50) 0
WaterDataSet Water data set RV=rivers, LK=lakes, GW=groundwater, TCM=transitional, coastal or marine waters, QA=water quantity. varchar(3) 0
