Characterize the Watershed

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.
