I am enjoying the information you provide and great scenery. I have a couple of comments re Colleges Crossing. There was a sand and gravel extraction on what was then adjacent to the river on the south bank upstream from the recreation area around the 70s. This created the wide 'lake' where the boat ramp is located. The river was hard against the northern bank but open to the lake area. The 2011 flood saw the river cut through the small inlet on the upstream side to the lake and create the island upstream. The flow is now directed to the upstream bank of the reserve with high erosion risk. Recreation is so popular that an overflow carpark was built across the road. Demand for services and infrastructure is high. I note that there is little woody vegetation in the historical photos. I doubt people would be very happy to have river access restricted by mass revegetation programs.
Hi Geoff - thanks for the additional information. The 1944 photo has trees along the bank which is what you need to stabilise the soil, but land clearing and erosion was already severe by that time. The erosion problem affects all locations that have been cleared, creating an ever wider and shallower river with poor water quality. We've seen it all the way up through the catchment. There's only one way to address the problem and that is riparian vegetation. Open recreation areas such as today's Colleges Crossing are suitable for lakes, and perhaps dams, but have no chance against the raging river. Next flood it will all get washed away again, together with another tens of thousands of cubic meters of soil which will end up in Moreton Bay. Re-vegetation would enhance both the recreation value and natural value my view, but the cricket and soccer games will have to be played elsewhere :-)
Colleges crossing had the best part of 10 years to recover and to get to where it was pre 2022 flood it will take time but will recover, as for colleges crossing the park its a great place and is wanted by many of the locals.
It's a really nice stretch of water. We have probably 4 legs to go until we reach the bay, so the next project will be a consideration for sometime in 2026 :-)

It was a really great day, Thanks for having me along for the stretch, I think you blokes are doing a wonderful job 🙂
Thanks Jason - we look forward to more joint outings in due course
Been waiting for this part for a long time and it does not disappoint
Thank you! It's a whole new environment from the Bremer and downstream.
Awesome to have you back on the river & posting again. Cheers. 🍻

That was excellent! Very well shot & informative. Nice to get a closer look at the area I've mostly lived in for nearly 25 years now. Cheers guys👍
Cheers Steve - its a great spot where the two rivers meet
It is. I've filmed it overhead by drone👍@@brisbaneriver-thewholejour2600
Good to see you two again.
Fantastic. Been wondering when the next ep would drop.
Thanks for sticking with us!

It's a great spot, just needs some mature vegetation to provide shade and reverse the runaway erosion.
Wonderful stretch of river. Completely agree about colleges crossing. Love the series. What river you guys hitting next?

great to see another leg of the journey . yes let the riverbank be native and wild 6:00
Thanks for suporting the cause - there's a lot of river restoration to be done across this dry continent
aren't you a bit concerned about damaging your kayak letting it smash over the rocky terrain like that?
Garry has a lot of faith in is Yaks - they have been through worse than that :-)
has the council still got collages locked up for no reason?
It's still a construction zone, hence the lock-up.

The Brisbane River bank changes when it floods, it has for a millennia, there's' no bogeyman.
Of course - but without vegetation the erosion becomes much worse. We've seen it all the way down the river.
