DATA SET ABSTRACT 3.1 Abstract of the Data Set The primary function of the stream watershed characteristics data is to provide a description of the watershed setting within which the stream exists. The data can provide insight into what the expected conditions in the stream are and insight into the extent to which human activities within the watershed impact the stream quality. 3.2 Keywords for the Data Set Watershed, land cover, land use, road density, human population, stream watersheds 4. OBJECTIVES AND INTRODUCTION 4.1 Program Objective In 1997 and 1998 the Ecological Monitoring and Assessment Program (EMAP) Surface Waters Program became a collaborator in the Mid-Atlantic Integrated Assessment (MAIA) project, which is attempting to produce an assessment of the condition of surface water and estuarine resources. The MAIA project represents a follow-up to the MAHA study, with an expanded geographic scope (southern New York to northern North Carolina, with more sites located in the Piedmont and Coastal Plain regions) and a different index period (July-September). 4.2 Data Set Objective This data set is part of the MAIA project to evaluate approaches to monitoring streams in EMAP. The data set contains the results of analysis of the stream watershed and its characteristics which influence stream quality. 4.3 Data Set Background Discussion Watershed information is gathered to describe the watershed setting, thus helping to define the "expected conditions" for the stream, and to describe the human activities within the watershed which are expected to impact stream quality. 4.4 Summary of Data Set Parameters Watershed Characterization parameters include physical characteristics such as watershed area, elevation, and approximate distance to ocean. They also include derived human influence characteristics such as land use categorization, housing unit and human population density, and point pollution source characterization. 5. DATA ACQUISITION AND PROCESSING METHODS 5.1 Data Acquisition 5.1.1 Sampling Objective To obtain a picture of watershed characteristics based on the most recent data sources which are available. 5.1.2 Sample Collection Methods Summary The watershed for each stream is outlined on a map and digitized into a GIS coverage. This coverage is overlain with other data sources, such as satellite based landcover data, or digital information on road networks, or data bases on point source discharges. The watershed intersection of these coverages is then summarized for each watershed and collapsed into a series of watershed characteristics or metrics. 5.1.3 Sampling Start Date May 1997 5.1.4 Sampling End Date September 1998 5.1.5 Platform NA 5.1.6 Sampling Gear Sun Work Station and ARC-INFO GIS software 5.1.7 Manufacturer of Instruments NA 5.1.8 Key Variables NA 5.1.9 Sampling Method Calibration NA 5.1.10 Sample Collection Quality Control See Lazorchak, et al. 1998. 5.1.11 Sample Collection Method Reference Chaloud, D.J. and D.V.
