Does sunlight increase or decrease the concentration of oxygen in the water of a creek?

I don't really know but I'm going to guess? I'd say in a creek there are algae and some form of plants or organisms that can photosynthesise. When the amount of sunlight increases, these organisms will be able to trap more light to photosynthesise more which would produce more oxygen. Hence the concentration would increase. I'm 80% sure this is right because it doesn't make sense for the concentration to decrease
