Description: This dataset holds the files generated by the Maine Geological Survey Snow Survey program. There are map output JPEGs for snowpack depth, snowpack density, snowpack water content, snowpack water content change, historical snowpack water content, mean hydrologic basin water content and an ASCII text file with the measurements for each site across the state. Snow depth, density and water content measurements are collected around the state at scheduled times each winter. MGS compiles the data and produces statewide maps for the Maine River Flow Advisory Committee. The maps assist with spring flood risk assessment and monitoring.
