An Adirondack Watershed Data Base: Attribute and mapping information for regional acidic deposition studies
The Adirondack Watershed Data Base (AWDB) provides a means to test hypotheses concerning the relative importance of various watershed attributes that may contribute to increased acidification of Adirondack surface waters. The AWDB is a valuable resource for the study of other ecological phenomena. The AWDB consists of digital watershed boundaries and digital geographic data, stored within a geographic information system, and watershed/lake attribute data stored in a data management system (SAS) for 463 Adirondack headwater lakes. Attributes include watershed morphology, physiography, bedrock, soils, land cover, wetlands, disturbances (e.g., cabins, fire, and logging), beaver activity, precipitation, and atmospheric deposition. Over 600 variables are available for each watershed. These data can be combined with water chemistry data and fish community status for regional-scale examinations of watershed attributes that may account for variability and change in water chemistry and fish populations in the Adirondacks. This report describes the design of the AWDB, documents sources and history of the data; defines the format of the AWDB contents; and characterizes the data using summary statistics, frequency bar charts, and other graphics. In addition, it provides information necessary for researchers using the data base on their own computer systems. 37 refs., 42 figs., 4 tabs.
