Description: Water areas are hydrographic features only and do not represent islands or uplands. Features were collected from water areas represented on the US Geological Survey's 1:24,000-scale topographic map series such as perennial and intermittent streams, lakes, reservoirs etc. A large portion of the DNR's unique IDs for waterbodies (Waterbody Identification Codes - WBICs) have been incorporated into the 24K Hydro layer, along with surface water names from the USGS Geographic Names Information System (GNIS). Wetland delineations are NOT included in the 24K Hydro data layer. More information, including a data dictionary, can be found on the Surface water (hydrography) data web page (http://dnr.wi.gov/maps/gis/datahydro.html).

Description: Flowlines include all line features from the US Geological Survey's 1:24,000-scale topographic map series such as perennial and intermittent streams etc. A large portion of the WDNR's Waterbody Identification Codes (WBICs) have been added to the linework along with officially recognized water body names from the USGS Geographic Names Information System (GNIS) database. Flowlines were created with M (measures) values to accommodate placement of user data through a linear referencing system. More information, including a data dictionary, can be found on the Surface water (hydrography) data web page (http://dnr.wi.gov/maps/gis/datahydro.html).
