1:24,000-scale Hydrography with Water Quality Classifications


Download Link: ftp://ftp.nconemap.com/outgoing/vector/hydro24k.zip
Abstract: Surface Water Classifications are designations applied to surface water bodies, such as streams, rivers and lakes, which define the best uses to be protected within these waters (for example swimming, fishing, drinking water supply) and carry with them an associated set of water quality standards to protect those uses. Surface water classifications are one tool that state and federal agencies use to manage and protect all streams, rivers, lakes, and other surface waters in North Carolina. Classifications and their associated protection rules may be designed to protect water quality, fish and wildlife, or other special characteristics. Each classification has associated standards that are used to determine if the designated uses are being protected.
Purpose: The dataset should be used in conjunction with the water supply watersheds data set and the high quality waters/outstanding resource waters data set as well as river basin waterbody listings (available at http://portal.ncdenr.org/web/ps/csu/classifcations) and applicable rules concerning reclassifications (15A NCAC 02B .0100-0317 available at http://portal.ncdenr.org/web/wq/ps/csu/rules) to get complete information on water quality classifications and associated rules applicable to surface waters. There are also rules and regulations associated with other state and federal programs as well as local governments that may apply to certain waters or land areas in North Carolina.
