PSAT

The Minnesota Phosphorus Source Assessment Tool

The Minnesota Phosphorus Source Assessment Tool (PSAT) is used to identify the relative contribution of sources of phosphorus to a lake or stream. It can be used to educate stakeholders about the sources of P in a watershed, and to identify further sources of information and analysis needed to understand and solve phosphorus problems in a watershed.
