they could build a place that would pump water out of the ocean

maybe with a filter to avoid pumping in sea life

and then ship it by train

or truck

lift a lot more that way

maybe in 5 years, pumping station + trucks, dumping water into a lake via a giant sluice

i mean that could get a lot of water in

maybe 40 times as much - 100,000 per year, or 500,000 cubic meters in 5 years

which is about 100 x 100 x 50 meters

there was an estimate on how much it would cost, but a billion a year is a bit of a big ask

so it could be 20 meters at the deepest point, 500 at the widest, and then 50 seomwhere

there was an estimate?

billion a year?

i mean all my idea is one pumping station, though it'd take a lot of power i guess

on maintaining bushlands

also trucks, which are typical

oh maintaining bushlands? well that's obviously different

i think they could just create the evac lake

maybe 1km wide, and the smoke doesn't get to people

depends on how long fires last for too

each boat has its own toilet

you'd have maybe 1000 boats lol

i dunno, seems like an diea

you could fit like 20 people on a small boat

10,000 boats - all the boats in the world

cmon, lets make this idea work

what's the population of NSW

fleeing to the lake probably can't be done, it'd just be a local thing

and maybe very expensive but i can make this work dammit

assuming a max depth of 20 meters for this lake

it'd have a surface area 24960

this is going off the 500,000 cubic meters of water fill

each boat might use 6 meters surface area (beam of 1.5 meters, length 4 meters)

20 people could crouch on it

if it has a toilet, maybe the length needs to be like 6 meters tho... or i guess people could just scoop their poop and pee out with their hands... it's a survival situation so who cares

i dunno how long brush fires last for

so there's no way that you could fit 10,000 boats in the lake... maybe 1000 or 2000 (if they're all touching close together... they don't want to paddle near the shoreline)

4000 is the maximum, if they are lining the shoreline and bumping each other

so 1000 boats - 20,000 people could be saved

but that's a local preparation thing

i dunno if the brush fire would keep going until they all die of thirst (lake would be salt water, since it's sourced from the ocean)
