Current status from this report

This report does not set a map status as of Nov 6, 2026, 1:03 AM PST. Check its dates and the status rules.

Published end not used: This report gives an end of Sep 8, 2026, 6:30 AM PDT, before the discharge began. An end that lies before the start, or more than 31 days after the site last read the report, is not used as the end: the status follows the rules for a report with no confirmed end, and the published end stays in the record as given.

1. Reported wastewater outlet

Operator named in the record: Porterville City (federal wastewater discharge permit, NPDES, 5SSO20008). Outlet: “W Mulberry and HWY 65”. Location: 36.08350, -119.03880; location source: given in the source record.

Outfall: a pipe or outlet where wastewater enters a water body.

2. Waters named in the notice

The notice names no water. No receiving water: the report says the discharge did not reach a water. The report is kept here but is not placed on a water and colours none on the map.

3. Estimated downstream stretch

We estimate routes only on rivers before they become tidal. We do not estimate routes through tidal water or lakes.

Map sources: water outlines and launches from OpenBoatLaunch and OpenStreetMap contributors (Open Database License); wastewater outlets from EPA and state records; downstream estimates by DirtyWaterWatch using U.S. Geological Survey maps and flow data. Base map: OpenFreeMap and OpenMapTiles.
