There is increasing emphasis on evaluating the results of our efforts to control nonpoint source pollution on a watershed basis. Evaluation must be an ongoing part of any watershed management, based on proper design and data collection. Three types of data are needed to evaluate watershed management projects: administrative, social and environmental. Evaluation or effectiveness monitoring is designed to measure the actual impact of management decisions, such as implementation of nutrient management practices (administrative, social) and resulting impacts of nutrient levels (environmental) in the waterbody. Environmental monitoring needs to focus on specific variables, take place in specific locations, and at minimum frequencies to provide a measure of whether and to what extent the water quality problems are being addressed. Instructors will present an overview of watershed monitoring, three watershed effectiveness monitoring designs, and identify issues to be considered when developing effectiveness monitoring programs. |
