Hi Clifford, Can you help me find something in the Skagit Delta that is tagged with the estuary tag? When I read your post, I immediately tried to check it out because I'm trying to understand how that tag is being used currently. But I wasn't able to find anything.
Thanks for your help. On Sat, Oct 26, 2019 at 9:29 AM Clifford Snow <[email protected]> wrote: > Looking at the US NHD estuary is broadly defined.
