This seems a little unlikely. I downloaded some of the NHD and I can't see how the original importer determined that these were salt water. There is a possible ftype in the NHD for estuary which would imply salt water, but the features I looked at didn't have this ftype.

All but two of them are intermittent bodies of water and those two were originally intermittent in the NHD import, but were subsequently edited. I suspect that the original importer made the assumption that intermittent implied salt water, or perhaps intermittent plus some other condition, such as no draining perennial waterway. In any event, I don't think this is a valid assumption. Rather than a mechanical edit, a better option might be to create a map roulette challenge. </div><div><br></div><div>Mike</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>
