I'm learning a lot today, Jane. Like not to be such a bird brain and focus on the water plants too. I'll take a walk out there again. If the river is low, there is a good chance we'll see it. Thank you.

A challenge ! Actually a few water plants turn reddish when stressed or stranded, not just Myriophyllum verrucosum. Leaf shape is hard to determine in these photos but it seems to be flattish, rather than the finely-dissected leaves of Myriophyllum verrucosum. This means it is most likely to be Ludwigia palustris: and especially because the habitat is just right (benthic muds of large river). See other sightings: 4508225, 4508178 etc.
With so little to ID, I'm uncomfortable verifying this, but am accepting it on the basis of habitat where found, and because effectively no other species likely to look like this or occur here.

the third photo was indeed helpful: gave an idea of likely whorl number, and showed overall shape. This species of milfoil has (nearly always) tight crimped hairs on the stem. If wading in is not possible, its worth checking the strandline for milfoil debris (waterfowl can be quite destructive) - these isn't good for photo portraits but can be useful source of species details.
Extra photos are really helpful
