- The document summarizes Chelsea Fougère's capstone GIS project for the Bluenose Coastal Action Foundation from May 2015. It involved creating databases of culverts and watershed delineation, as well as mapping water quality time-series data for rivers in the area. - Key tasks included distinguishing lakes from rivers in the data, building a culverts database in Excel, flattening lake and river elevations, modeling watersheds and barriers to flow, and preparing time-series data on temperature, pH, conductivity and dissolved oxygen for mapping and sharing. - Lessons learned included the importance of data preparation, avoiding assumptions, and having contingency plans when issues arise.
