A missing USGS station #22

Closed cheginit closed 2 years ago

cheginit commented 2 years ago

The following USGS station is not indexed:

ID: 04127918 nhdplusv2 comid: 12206226 nhdplusv2 reachcode: 04070002000042

cheginit commented 2 years ago

I found two other stations:

ID: 02084557 nhdplusv2 comid: 1967611 nhdplusv2 reachcode: 03020104000870

ID: 10172200 nhdplusv2 comid: 10389446 nhdplusv2 reachcode: 16020204000450

Are you sure about those last two? I don't have time to dig into things (and I found a bug I need to fix) but it seems like they are not really in the vicinity of the gage. Maybe I'm not looking at things right.

cheginit commented 2 years ago

These are the flowline-station distances in meters:

I used NLDI's position endpoint to get the nearest comid. The last two sound far from the stations.

dblodgett-usgs commented 2 years ago

OK -- yeah, that's what I'm seeing.

So it seems like there just is no flowline for the two that are far away?

cheginit commented 2 years ago

No, there's no nearby flowline in nhdplus mr, but there are in nhdplus hr:

OK, re: the one you found missing, I found the issue. It was superseded by 04127917 -- but the record wasn't combined. In my source of network locations that is the highest quality, they dropped 04127918. I will bring these cases back in our next release of locations to the NLDI.

dblodgett-usgs commented 2 years ago

Regarding the ones that are far from a medium res flowline -- I don't think we should put those into the NLDI as indexed gages. We don't currently have a hybrid approach though. I just opened https://github.com/ACWI-SSWD/nldi-crawler/issues/126 to track the issue.

FYI -- @cheginit the site that was the original source of this issue has been fixed. https://labs.waterdata.usgs.gov/api/nldi/linked-data/nwissite/USGS-04127918?f=json

That's great! Thanks.
