why is it surprising that usgs calls it a gut sloughs are often guts there is nothing in this article that indicates it is anything but a gut or slough not an estuary the friends may be a reliable source who knows i'm told that if blogs say something in agreement it can be considered reliable information if there are no reliable sources that say it's an estuary that information should be removed i would tag it as inaccurate but i am under threat of permanent community ban if i should question facts on wikipedia in articles it's your article you want to call a slough an estuary okay i would just like readers to know it's unsourced information that appears to have nothing in the article backing it up i've done that i wash my hands of this inland stagnant water estuary
