One component of this initiative aims to improve current understanding of nutrient dynamics and cyanobacterial and harmful bloom (cHAB) occurrences on Lake of the Woods. Research will focus on investigating the sources of nutrients and additional mechanisms influencing cHAB development and transport on the lake, determining cHAB composition and toxicity, and improving lake-wide monitoring capabilities through remote sensing observations. Results will document the status, trends, and drivers of blooms, and the risk they may pose, in order to inform on appropriate management and mitigation strategies. Here, as part of this effort, phosphorus concentrations are being provided. It is anticipated that other water quality data will be provided once available and quality assured.
