Colours no water as of Nov 2, 2026, 6:56 AM EST: the windows on the methods page have passed, or the record has no time to count from.
A report is not a test of the water. See how statuses are worked out.
1. The reported outfall
Outfall reported by CITY OF NEW BEDFORD (MA0100781 outfall NEW003): “COVE RD & PADNARAM AVE”. Location: 41.61243, -70.93039, from the state's or EPA's outfall layer.
2. Waters named in the notice
The notice names: “CLARK COVE”. We place it on Clarks Cove, MA. Matched by the name of the water in the source record.
3. Modeled downstream reach
Not modeled: the reach model runs on rivers above the head of tide only.
Source: water outlines from OpenBoatLaunch and OpenStreetMap contributors (ODbL); outfalls from EPA ECHO and the state outfall layers; modeled reaches computed by DirtyWaterWatch from USGS NLDI, NHDPlus and the nearest USGS gauge (Jobson 1996); basemap OpenFreeMap and OpenMapTiles.
When: three different times
The time of the event, the time the source reported, published or updated it, and the time we fetched it are kept apart. Times are shown in New England time; the record keeps the original offsets.
