Focus on lakes here maybe be a small point in the larger picture. Consider the possibility that organic compounds may be forming into consistent and deliberate reactions in the viscous atmosphere, falling to the planet surface as well. The suspension, theoretically, doesn't necessarily need to be a dense as liquid and who knows, an ATM of 5 and a good dice roll, may be the 'primordial soup' yet unknown.
