Images sharpened, then compared in color spectral density processed on high end computer system/graphics high DPI w/32bit color . Results are is that this is not an exposure change but a real coloration change in the water. The circled image areas were analyzed (spectrally). What is also an independent proof is that the coloration of the side stream to the left maintains its same hue/saturation/contrast etc while the brown color flow on the outside of the main spillway sidewall turned brown (compare left circles in both images). This indicates a soil erosion "burst" in the main spillway hole cavitation/hydraulic turbulence upstream.

Death knell for the main spillway.

She’s gonna blow Captain.

I wonder if they can even shut it off?

There is a break in the dam in front of the weir or just behind it on the dam side?

Is there any possibility of that brown water coming from the side of that big @$$ hill that is dividing the water flow?

What did you do to compare color spectral density? Are you just talking RGB histograms? Both images are so poorly exposed from a detail retention perspective (there is no detail in most of the water due to overexposure) that it is hard for me to say with confidence that the drastic change in the local coloration is due to increased sediment. It probably is sediment given the context, so I’m probably suffering from a little bias here! Just curious what you actually did to come to your confident conclusion.
