Watershed management is of great interest to water purveyors because of recent events and publicity. Purveyors use strategic watershed plans to avoid the costs of expensive treatment plant upgrades. Evaluating and taking advantage of existing programs are important components of such plans. Purveyors must understand, communicate and cooperate to succeed in taking advantage of existing programs. This paper focuses on evaluating existing watershed programs which includes maintaining: barriers to watershed access, regulating land use and pollution sources, monitoring water quality within the watershed, communicating, and monitoring activities within the watershed.
