Determination
Check a property
Pick the town, then the watershed. You get the statement that currently applies, the filing that supports it, and the sources so you can verify every step.
Not sure which one? Look the address up on MassDEP's address map — click the green area and read Estuarine System Name. The map's names are longer than the names in this list. Match on the opening words, or use the table below.
This is a reading of public records, not a legal opinion. It reflects MassDEP's
watershed application table dated 11 June 2026. Filings change. Confirm with your Board of Health
before you sign anything.
