Characterizing the watershed, its problems, and pollutant sources provides the basis for developing effective management strategies to meet watershed goals. The characterization and analysis process helps you focus your efforts on the most critical needs and targets your data collection and analyses within the watershed. The scope is defined as not only the geographic area to be addressed but also the number of issues of concern and the types (and breadth) of the goals you want to attain. If you define your scope and set preliminary goals early in the planning process, you will find it easier to work through the later steps in the process.

The Nature Conservancy's Aquatic Ecosystem Classification Framework - Explains the Nature Conservancy's approach in establishing freshwater priorities across large geographic areas. This site provides access to documents, papers, GIS tools and data related to this approach.
USEPA TMDL Compendium of Tools for Watershed Assessment and TMDL Development - The Compendium of Tools for Watershed Assessment and TMDL Development supports the watershed approach by summarizing available techniques and models that assess and predict physical, chemical, and biological conditions in waterbodies. It is intended to provide watershed managers and other users with information helpful for selecting models appropriate to their needs and resources.
EPA CREM (Council for Regulatory Environmental Modeling) - Allows the user to access a wide variety of modeling documents and information.
