If you require support for NHDPlus or would like to receive occasional emails about the availability of NHDPlus data, tools and updates, send your name, phone number, organization, and email address to NHDPlus Support.

Effective January 1, 2011, the NHDPlus team is focused on building the next version of NHDPlus (NHDPlus Version 2). The Build/Refresh process is intensive and will consume most of the available NHDPlus resources until September 2011. Consequently, NHDPlus support for both data and tools will be very limited. The NHDPlus Team appreciates your understanding.
