Anyone else willing to offer a theory?

Simple high school physics explains it. Because the lake has more volume than the marsh. Equal evaporation but different ratios of water to salt.

Go mix a 5 gallon bucket with salty water. Pour some in a quart container. When the quart is evaporated down by lets say half, it's going to be saltier than the larger container. And the larger container will not have evaporated in half during the same amount of time.
