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.
