Benthic Monitoring Sites


Download Link: http://data.nconemap.gov/downloads/vector/benthic.zip
Abstract: The North Carolina Department of Environment and Natural Resources, Division of Water Quality, with funding from the NC Clean Water Management Trust Fund and in cooperation with the NC Center for Geographic Information and Analysis, developed the digital benthic monitoring data to enhance water quality assessment & plan review of Trust Fund project applications. This file identifies points where benthic macroinvertebrate monitoring has occurred. This file enables users to review the current rating of water quality for each sampling site based on the monitoring results.
Purpose: These data were created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).
Supplemental Information: system filename : bmr approx file size = 0.34 mb Revisions and updates to this layer include: 2) filename: bmr900 CGIA received from DWQ an excel spreadsheet with a list of benthic monitoring sites through November 15, 2000. This spreadsheet contained many latitude and longitude corrections from the original layer released by CGIA. This version includes two additional attributes: basinsite, which indicates whether a site is part of a routine sampling schedule, and sample type. 1) filename: bmr600 The June 15, 2000 version was the first version released to the database. Original was data received and processed September 1998. Corrections to lat/longs were made in October 1998. Minor latitude attribute correction was made June 2000. (The coverage's projection was also defined.)
