EPA Delineate

Mar 10, 2012 at 7:59 PM

Is seems like New Mexico has issues with the EPA delineation.  Does a state actually need to have water before it can delineate basins? 

I'm getting 'Error searching for watershed. Unterminated string. Expected delimiter: ". Line 1, position 119.'  for just about everywhere I try in the state.  Other regions are working fine. 

Any tips from gurus?

I've also tried delineating watersheds in New Mexico without success. The only part of NM where delineation gives results is in the Canadian river basin.

This is a known issue in the EPA Delineation tool - the EPA Delineation web service doesn't have the streams in New Mexico Rio Grande basin connected to the NHD+ network.

The change I made in HydroDesktop 1.4.10 is now correctly displaying the actual error message returned by the server: "The selected flowline (stream segment) is not connected to the NHDPlus stream network". instead of the user-unfriendly error.

I've contacted the EPA Waters team and asked them what is the schedule for supporting new Mexico.

Thanks for the update Jiri.  Hopefully the EPA will get around to including us soon.  Basin analysis is even more important when you don't have much water.

Thanks again,
