It could just be rusty. Car coolant systems are ment to be used with a mixture of coolant and water. Only having water does a few things car gets hotter faster, more water evaporates and u can have some rusting. If it was me I would flush it out very simple to do and if it's time to change you oil and something was wrong I bet there will be water in ur oil if there is oil in your water. I still leaning more towards rusty water, does you car get hot?

Is this an LS engine? If it has oil in the cooling system the radiator cap in your picture the rubber will be all swelled up, which it doesn't appear to be, the radiator hoses will be very soft. If the engine oil is mixed with coolant, will be a milkey color in the oil pan. Otherwise to me looks like rust/corrosion.
As far as water evaporating..... Cooling systems are a closed system and should not evaporate any water. If yours is then you have a leak somewhere.
Antifreeze does go bad and should be changed periodically.
