Temporary NHD and WBD Maintenance Shutdown and Hydrography Tools Updates

April 14, 2021

NHD and WBD maintenance operations will be shutdown from close of business April 23rd to May 9th. 

Additionally, USGS will be releasing updated versions of all Hydrography tools during this time. Check-outs beginning May 10 will use the ArcGIS 10.7.1 compatible tools.

USGS is upgrading our technical operations data center to new hardware, as well as moving several servers and operational systems between Denver, CO and Rolla, MO. Due to this, all WBD and NHD jobs must be checked back into the national database.

  • WBD jobs must have been submitted by 5 pm MST April 5th to allow time for NQC review. 
  • NHD jobs must be submitted back to USGS by close of business April 23rd.

During this shutdown, other HMP functions are still available. For example, state contacts, USGS point of contact, and state MOUs information will be available using the map function. Reporting will also be functioning, so users can generate job histories.  

Also during this shutdown, USGS will be releasing updated versions of all hydrography tools that work with ArcGIS 10.7.1. Partners are encouraged to use this time to update their systems. Data check-outs beginning May 10 will use the 10.7.1 tools.
