This doesn't cover what you're proposing to do, but it may be worth taking
a look at and possibly collaborating with: https://riverlevels.uk/map
It doesn't just have locations of monitoring stations, it shows their
current levels (it used to also show a graph of historical data but
that seems to have gone).  It also shows flood zones:
