Yes, indeed. Speaking as an earth scientist, I can vouch that it's historic. Just imagine, the sediments that are being brought into the lake (contributing to low vis, of course) will eventually settle and become a fine layer on the bottom. One day (perhaps many moons from now, if Texas weather patterns are any clue) other rains will bring in more such sediments. Eventually, in the long course of geologic time, these layers could become compressed strata of rock. Therefore, this ample plethora of silt laden waters coursing into the lake is, without a doubt, hysterical...er, historical.
Okay, now before I get flamed, you do realize that this was all tongue in cheek, right?
