Morrison is fairly clear. I was surprised since there has been some rain this week with a couple of storms yesterday afternoon. The viz is at least 12′ on the upstream side of the basin. It looks like there may be some dark water on the downstream side but I’m not sure, as I was up on the SCUBA dock and not in the water. There were a few oil blobs, but no big slicks, and some leaf litter in the water but otherwise nothing gross.
