I've noticed something strange this trip to the lake. Mussel growth on the rocks at the current water level (3601-2) is nearly non-existent. These rocks in the photo below have been underwater for nearly a year and there are very few mussels on the rocks just coming out of the water - in some places zero mussels, in others, just a few on the underside of rocks, but overall, very few mussels are visible at the water level and above in any of the canyons I've visited. In the past few years, when the water went down mussels on the side of canyon walls after only a year, including Castle Rock Cut, have been significant. There is definitely something scientifically different than the past few years occurring. The water is extremely clear, and mussels seem to be fewer at least at current water levels.
