Looks like the water coming from under the spillway is now flowing down the closest rocks to the spillway.
Not much water, but still.
Also looks like something going on on the left side (to us) of the spillway.
I know how strong water can be.
Otter Creek at Fort Knox, KY. Pretty little creek. Washed 100 tons of steel down the creek one day (M88 Recovery Vehicle towing an M60 Tank).
I seem to recall Juan saying the spillgates are designed to let some water trickle through or else sediment would build up.
But there was a mixer truck there a little while ago.....
Might be an issue indeed. Not major...yet.
