Test students' ability to analyze how watershed land-use patterns (agriculture, urban, forested) drive nitrogen and phosphorus loading and influence algal bloom occurrence in temperate lakes; scope includes interpreting land-cover and hydrological data, distinguishing point vs nonpoint sources, applying simple load-estimation and correlation methods, assessing seasonal and watershed-scale drivers, interpreting monitoring and remote-sensing indicators of blooms, and proposing targeted monitoring and management (BMP) strategies while critiquing study design limitations.
