National Hydrography Dataset Newsletter March/April 2021 - Vol. 20 | Issue 3/4

We're excited to share information on new open-source projects using NHDPlus datasets, as well as general updates. Also, please see important information on necessary data check-ins for stewards, updating tools to ArcGIS 10.7.1 versions, and errors in NHD downloadable datasets in March (including how to get corrected data!).

~ Enjoy!
