...
thank you .. I remember something about that now. has anything been put out by anybody about the purpose of all that concrete..?
why are they putting an apron there?
Quoting: ALL IS ONE IS ALL I am not sure which concrete you are referring to. To the left or right of the spillway from the bottom camera view? the concrete being laid as an apron is OBVIOUS on the hillside between the main spillway and the Dam itself... its all been stair stepped and they are dumping concrete on it. AS YOU FACE the image of the lower spillway.. it would be on the riight... There is more on there every working day. [ link to www.parks.ca.gov] Looking at the bottom camera view to the right, I see 3 terraced hillsides. The topmost has a green hue, indicating it has been hydroseeded for erosion control. The two lower hillsides are still bare. The only concrete I see is an apparent drainage channel lined with cobble, to drain the hillsides toward the river. I don't see any other concrete. I DO. the dark gray areas have been spreading for days... Thanks for explaining the green stuff. though! One of the stair stepped areas is becoming smeemed with gray... what else would be gray like concrete gradually being spring... were is the bent gray channel with the gravel or whatever going to drain what? It is new also in the last days... Does the seeding look gray at first? I shall watch for color change as it sprouts if that is what it is.
