River in Rhode Island · near Cranston, Pawtuxet

Status now

No current report

At least one source we follow covers this water, and nothing it reports applies right now.

Why this colour: No current report: nothing a covering source reports colours this water now. How long a water stays coloured, and why

Source: ECHO NPDES Sewer Overflow and Bypass Event Dataset (eRule Phase 2, current versions), last answered 2026-11-02 11:54 UTC; ri-echo-dfr, last answered 2026-11-02 11:55 UTC. Status computed by DirtyWaterWatch as of 2026-11-02 11:56 UTC.

It is not a finding about the water. Discharges go unreported, reports arrive late, and storm runoff carries bacteria too. Follow posted signs and local health advice.

Rivers are not coloured as a whole: a discharge colours a modeled stretch downstream of its outfall, listed below when there is one.

As of Nov 2, 2026, 6:56 AM EST.

Map

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.

Outfalls are small brown dots.

Modeled downstream reaches on Pawtuxet River

No discharge colours a modeled reach on this water now.

How these charts are counted

Discharge events are counted once: where a source publishes both public notices and verified reports (MassDEP, Vermont DEC), a discharger's month with any verified report counts its verified reports only, and other months count notices. Revisions are folded into the record they revise, and EPA copies of a state report are not counted twice. Monthly and yearly totals (Maine DEP, EPA discharge monitoring reports, Portsmouth) are shown on their own and never added to the event counts. Hours under advisory follow the map's red rules. A muted band marks periods no source covers: a gap there is missing data, not a quiet month.

  • EPA ECHO sewer overflow events: 2022-05-03 to now (sparse)
  • EPA ECHO facility reports (RI): 2024-02-11 to now (sparse)
