Are there actual measurements that even show this deoxygenation?

For example, I clicked on the random link in that paper (referenced as a proof of river oxygen decline) — the article was not even based on some actual data log but fucking deep learning model (which may or may not work)

Yes, the organization I work for studies this phenomenon extensively. We measure pH, temperature, oxygen, flow, and many other factors related to ocean health, and over time, climate change. Hypoxia (and acidification) are emerging concerns.
