A report is not a test of the water. See how statuses are worked out.

1. The reported outfall

Outfall reported by SPRINGFIELD WATER & SEWER COMMISSION (MA0101613 outfall SPR048): “ALLEN & RIFLE STS.”. Location: 42.09703, -72.56393, from the state's or EPA's outfall layer.

2. Waters named in the notice

The notice names: “MILL R.”. We place it on Lake Massasoit, MA. Matched by the outfall's ID in the outfall registry, which places each outfall on a water.

outfall MA0101613 048 (geometry, 95 m)

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.
