The California Department of Water Resources (DWR) now receives funding to act as steward of the California portion of the National Hydrography Dataset (NHD), which includes the Watershed Boundary Dataset (WBD). For more information on that program please visit the DWR website at https://water.ca.gov/Programs/All-Programs/National-Hydrography-Dataset-Stewardship

In September 2022, USGS officially notified DWR that the NHD will become static in 2023 as USGS resources will be devoted to the transition to the new 3D Hydrography Program (3DHP). 3DHP will be easier to maintain, be based on a modern data model and architecture, and better meet the requirements of users that were documented in the USGS Hydrography Requirements and Benefits Study (2016). Please refer to the resources on the National Hydrography Dataset page on the California Natural Resources Agency Open Data site for more information.
USGS has allowed users of the NHD and WBD to report errors to these datasets by using their Markup Application. As of December 1, 2022, markups will no longer be accepted. Users of the NHD may contact the lead California steward directly to report errors through December 15, 2022. After that time, we will most likely be unable to process corrections to the NHD. You may contact the lead steward by email at nhd_stewardship@water.ca.gov if you have any questions about this or about other hydrography-related issues.
This dataset was created under an MOU between many government agencies in 1998 and then updated in 2004 and version 2 of CalWater was released; responsibility for maintenance of Calwater was shifted to DWR. In a letter signed August 3 2017 and mailed to the signatory agencies, DWR establishes that version 3 of Calwater is the Watershed Boundary Dataset as it appears in The National Map, and no further updates to Calwater 2.2.1 will be made.
