What you're talking about is an estuary situation. We have a similar thing near here but not called a guzzle, just a channel.
Google map of Trent Water estuary at Bridport
From the above satellite image taken at high tide you can see the "guzzles" as ribbons of darker fast flowing water. The car ferries come in on these channels, but sometimes they get stuck on the sandbanks in between.
In the picture below of the same place, the tide is out leaving only the deep channels.
