How do I complete this thing?!

I played TTD for the first time in about 10 years. I played 'New Game' and I'm now stuck and can't win the game. Is it impossible to beat 'new game'? I'm sat on 400mill and have pretty much removed all the water from the land. I think this game has been running something like 72 hours... HOW DO I WIN?! lols.
