Waterbase-Lakes: Stations

Data Table

This page was archived on 07 Jul 2014 with reason: Other (New version data-and-maps/data/waterbase-lakes-10 was published)

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
