A report is not a test of the water. See how statuses are worked out.
1. The reported outfall
Outfall reported by an operator the record does not name. Location: 44.93811, -72.21750, given in the source record.
2. Waters named in the notice
The notice names: “Lake Memphremagog”. We place it on Lac Memphrémagog, VT. 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.
