Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, projects, and programs to sustain and enhance watershed functions. The functions of watersheds in turn can affect the plant, animal, and human communities within a watershed boundary. Watershed management is the process of organizing and guiding land and other resource use on a watershed to provide desired goods and services without adversely affecting soil and water resources.
Embedded in this concept of watershed management is the recognition of the interrelationships among land use, soil and water and the linkages between uplands and downstream areas. Features of a watershed that agencies seek to manage include water supply, water quality, drainage, stormwater runoff, water rights, and the overall planning and utilization of watersheds. Landowners, land use agencies, stormwater management experts, environmental specialists, water use surveyors and communities all play an integral part in the management of a watershed.
