The Office of Water Resources maintains a network of approximately 150 precipitation observation stations throughout Massachusetts. We also maintain a precipitation database which may be used for many purposes and which is available to the public. 

Precipitation Database

DCR's Office of Water Resources maintains a precipitation database that is updated monthly using reports from our observers and cooperative agencies. Precipitation values in the database are totals for each station for each month. Snow and ice are melted and reported as inches of water.

Data from the Precipitation Database is currently available to the public in Microsoft Excel format. Data is sorted alphabetically by station and then listed by year. Note: The unit used for precipitation data is inches.
