“I have noticed on more than one web mapping application that a significant local stream has a name which is not consistent with what it is known as locally. The source of this error is the NHD dataset. I am wondering how I can get more information on this and possibly how to get it corrected. This waterway should be named Johnson Creek, not Davis Creek. ”
Type of edits needed
“Thank you for bringing this error to our attention. The NHD feature name is incorrect and should be attributed for Johnson Creek in Clackamas County. The Davis Creek entry appears to be correct in the GNIS, but was applied to the wrong feature in NHD. The correction to the NHD dataset has been noted and will be applied by an NHD editor. ”

“The new tools and help documents/videos are great. These would have saved maybe 40% of the time on our project.”
