Abstract
These data layers represent hydrography for Rock County, Wisconsin in 2015. It is a feature class within the geodatabase, “Rock_Hydro_2015.gdb”. The feature layers included in the geodatabase are “Rock_HydroPoly_2015” and “Rock_HydroLine_2015”.HydroPoly: [This is an ESRI Feature Class of the Hydrology polygons in Rock County, Wisconsin. This dataset is being used as a base for the Rock County Hydrography re-delineation project.The methodology used to construct this feature class used numerous datasets as reference and verification of active hydrography within Rock County. The datasets used were: USGS 7.5 Topo Quad Digital Raster Grids, 2004 and 2005 NAIP Aerial Photography, 2005 and 2006 Pictometry Oblique and Top-down Orthophotography, March of 2000 Orthophotography, March of 2000 Digital Terrain Models, March of 2000 2 Foot Contour Topography. The primary data layer of reference was the USGS 7.5 Topo Quad Digital Raster Grids for Rock County. The attribute field "Pres_USGS" refers to the presence of the hydrology depicted on the USGS maps. As many of these maps were created decades ago, secondary and tertiary reference and verification of the extent and delineation of the hydrography was done using other current orthophotography and digital data such as terrain modeling, and 2-foot contour topography. In some cases, the extents, delineation, and configuration of the hydrography was adjusted to current (2006-2007) conditions based on this newer, more accurate data.]HydroLine: [This is an ESRI Feature Class of the Hydrology "line work" in Rock County, Wisconsin. This dataset is being used as a base for the Rock County Hydrography re-delineation project.The methodology used to construct this feature class used numerous datasets as reference and verification of active hydrography within Rock County.

Purpose
This layer is intended for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data. [The redigitization of the Hydrography of Rock County is needed to effectively support ordinances within the County such as: The Rock County Floodplain Zoning Ordinance and the Rock County Shoreland Zoning Ordinance. The previous hydrology layers were digitized in 1996 by several participants from the Planning and Development department using early low-resolution orthophotography. At the time, the project represented the best methods and technology available. As the use of this data has increased over the past 10 years some errors and inaccuracies have been identified. In addition, as technology and data accuracy has improved, it has become apparent that the hydrology of the county requires redelineation using today's best practices.]
