One from the archive. Actually a bird photo but the plant might be identifiable in context. The Bidge in drought.

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.

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.
