Obviously if you take a pic at high tide or especially in a storm the water level is going to be higher.
Why don't you ask around the old folks who have lived at Applecross or some other suburb on the river if they have noticed the river rise in their lifetime.
I think you are forgetting that the Swan river is nothing like it used to be before whitefella created Fremantle harbour...
Prior to C.Y. O'Connor using vast quantities of Alfred Nobels finest products to break up the rock, followed by a massive dredging operation to clear the river's mouth, the Swan was pretty much like the Moore river - most of the time it was blocked until the built up river water breached the barrier, then the river would drain out until the levels equalised, until it was blocked again by sand clogging up the gaps between the rocks.
The present level of the river is dictated by tides slowing the outflow - it is nothing like how it used to be back when the early explorers dragged their whaleboats through the river mouth, then having to row through the masses of birdlife that practically covered the surface of the water.
Whenever we have an exceptionally high tide coinciding with run-off from decent rain [whatever that is] we have minor flooding.
I have driven through hub deep water on riverside drive plenty of times / even hub deep on the freeway at South Perth.
You also forget that much of our riverbanks are nothing like they used to be "before whitefella" - much reclaiming of swamps, riverbanks were walled up, stormwater from all around the Perth metro being funnelled into the river, water being pumped, drained and transferred between lakes and out to the sea at various beach outflows.
Lake Monger and Herdsmans lake were both much larger, and used to be practically joined - and much of Osborne Park was soggy until we filled it in with rubbish!
Comparing our river today, [and Perth's remaining marine environment] with how it used to be before we stuffed it up just isn't an honest way of proving global warming or climate change - all it proves is we butchered the area we live in.
