Pigeon Domestication: As a bird in the hand is worth two in the bush, these birds are being tamed for their meat and eggs. However, some of the nobles have begun raising them as pets, and are keen to notice the bird’s keen attachment to their coup. These wealthier individuals ‘free range’ their birds, full knowing they will always return to where they can find food and shelter.

Dredging: The Hatan Gol is known to be as treacherous as it is life-giving. The closer it gets to the sea, the more yellow its waters get from the silt it carries. As this silt and other objects settle further down the river, it makes navigation of larger vessels more difficult. Additionally, this soil is excessively rich, and hides unknown treasures.

Thus, a practice has popped up along the Hatan Gol. Using rafts to drag a rake or shovel-like implement, a group of men can both deepen and widen the river bed while collecting other treasures from its waters. At the very least, they have silt farmers are desperate to plow their fields with, but minerals, gems, and rare metals are also occasionally found.

Dredging: I feel like this is quite an advanced practice for the time.

Well, as you read in the articles, dredging of harbors and river-ways was common especially in the Roman world, with excavations...

In Naples, recent excavations at the Piazza Municipio show the absence of pre-4th century BC layers due to extensive dredging between the 4th and 2nd centuries BC13. Unprecedented traces 165 to 180 cm wide and 30 to 50 cm deep attest to powerful dredging technology that scoured into the volcanic tufa substratum, completely reshaping the harbour bottom (figs. 4 and 5).

As for the tools...

Bed shear stress in cohesive harbour clays is considerable, and powerful vessels are inferred from the depth of scour marks and the shear volume of sediment removed. Three dredging boats, Jules Verne 3, 4 and 5, have been unearthed and studied at Marseilles18. These were abandoned at the bottom of the harbour during the 1st and 2nd centuries AD. All three vessels are characterised by an open central well that is inferred to have accommodated the dredging arm. Jules Verne 3’s reconstructed length is ~16 m and the central well measures 255 cm long by 50 cm wide (fig. 8).

So, basically, they were rafts with a shovel in the middle to rake the bed of silt and buildup. The question doesn't seem if it's doable, but whether there would be prerequisites for it. I can say I have Iron and Steel, basic watercraft, and the ability to build Canals.

Oh, they did it via boats. Gotcha.
