Return To Baihe Reservoir (白河水庫) To Observe New Sluiceway Construction

Late - very late - on Saturday afternoon, I took the girlfriend up to see Baihe reservoir on account of the new sluiceway construction. This would be my first look, and repeat trips are in order to observe the ongoing construction over the coming months...

A view eastward from the dam crest over the south-western "front" of Baihe reservoir in its' current, drawn-down, state. The reeds growing out of the sediment have now extended so far that they cover what might be as much as 10% of the reservoir's entire surface area, most of which is not visible from this perspective.
Panorama from the far north corner of the dam past the spillway; what remains of this section of the reservoir is simply the river's original route (center) and an additional channel (left) leading to both the northern and eastern areas of the reservoir which are obscured from the public view by the intervening geography.
Tonnes of sludge-like sediment built up behind the spillway gates over the past sixty years or so.
Detail on the original route of the "white river" into the reservoir; this route is kept alive by the use of excavators to remove sediment, otherwise it would already be a marshland and no longer a reservoir. 
I honestly don't know what this is.
Look what this river is reduced to as it squeezes its way through the fields of mud.
Another detail on the "white river" as it trickles past rows of reeds standing upon six feet of sediment deposits.
Plan for the new sluiceway.
This was the best close-up shot I could manage; for some reason the image rendered on the metal sign itself is not clear.
The whole public notice giving the usual official details; it actually began in April of this year, after my trips to Nantou County, and is due to be completed in October 2018.
The top of the new access road, with drilling work being carried out just next to it.
A late view eastward toward the dam and the new sluiceway from the Beitou Society park.
The last light of sunset reflecting from the metal surfaces of the spillway control building.
Detail on the end of the spillway, with the dirty, mud-grey water spilling over the final wall and into the channel.
The downstream end of the new sluiceway, with wooden latticework still in place for the forming of fresh concrete.
The parallel walls of the new sluiceway curve uphill toward a bare section of hillside which has already been partly dressed in concrete in preparation for the drilling, which will take place through the earth below.
The new access road meandering its way downhill to the confluence of the old spillway and the future sluiceway.
Me and girlfriend at the far northern corner of the dam.
