Oxbow lakes - how do they work?
Well, I can tell you even now, 45 years or so after the event…
Oxbow lakes came up in every year’s end-of-year geography exams four years in a row when I was at secondary school, and then again in the GCE O-level mock exams and then again in the actual GCE O-level geography exam itself. I still remember every detail and have developed a life-long love of seeing a meandering river in a flat valley with oxbows here and there.
(Yes, I passed geography GCE O-level!) :wink:

As soon as someone owns the property bordering a river, the tendency is to want to make it not meander and to control it. There are consequences.

Meanders are often used as a gardening feature. We went to Innisfree Garden for Mother’s Day and there is a really stunning example; tucked under a series of feature gardens leading to a pear orchard. Of course, it was surrounded by spring perennials and trees just leafing out, but this garden is gorgeous year-round.

That said, why am I expecting an executive order to close and/or demolish the Old River Control Structure?

New Orleans, LOSER town! Glory,if it had any, long faded. Time to go! #MAGA

We’re dealing with that in LA, too:

So, that’s why they call it “Oxbow Park”. Interesting. The Sandy River does take a few loops where the park is located.

Well done on the O-Level, but you didn’t tell us how they form!

:wink: Watch the video. Mostly you got full marks for accurately reproducing the four stage diagram showing how. Like the version here - scroll down a tad, perhaps.
