Since there is no way to make the flume one long continuous trough, there will have to be a pump house for the island and also for the park side of the ride. Pumps are needed on each side to get water to the top of the lifts.
I could be way, way off, but I don't think the water being pumped over the lift hills is anything more than cosmetic.
It appears as if the big blue pipes (protruding vertically to the right of the station, beneath the first lift hill) are where the water is pumped. That big pool includes the splashdown area, after which the water travels "down" the flume through the station and to the base of the lift, where it is pumped "up" back into the splashdown pool. Notice how the flume, after leaving the splashdown area, maintains a continuous separation from the main pool. It's essentially a slow, giant version of one of those tabletop waterfall things. You can see the flume-pool separation best in the Shoot the Rapids renderings.
That same process happens on the island, where the water is pumped from the base of the 2nd lift, "up" into the splashdown pool (the blue pipes are behind the base of the lift), where it travels out and "down" the flume. The only difference on the island is that the flume protrudes back into the main pool (though of course it maintains the necessary separation).
Again, I could be way off, but that's what it looks like to me.

hard to see, but are those guys beginning to do the steel sub structure for the rock work near the final run out?
There is one critical error in the way that the island splash pool is drawn in the rendering....That being the termination of the flume is shown open to the splash pool which would not work in terms of the water flowing down the flume as both the inlet and outlet of the flume would be at the same relative water level.... The islands flume in fact is closed off from the main pool and water is pumped from the end of the flume back into the main pool just as you have described.
In as much as the reseviors are located at the top (or head) of the system, it follows from this that the movement of the boats is due solely from the pumping of the water and not due to any "slope" from the beginning of flume to the end. Otherwise the entire pool would spill over the end of the flume during the resting state (pumps off).
You may prefer that, however, general forum etiquette across the tubes says otherwise (as do other's reading preferences). But I digress...
The ride is really starting to take shape, and I'll be interested to see what - if any - theming elements get put up outside besides things like rock work and landscaping. While I am not at all disappointed that I won't be there to ride it when its open, I am disappointed that I won't be able to take pictures of it. :)

Three things you need to fix anything in the universe: duct tape, WD-40, and a hammer. Duct tape if it moves and it shouldn't, WD-40 if it doesn't move and should, and the hammer as the last resort.
i dont find the double posts nearly as annoying as the little tag things you all seem to like to put at the end of all your posts which do in fact get repeated over and over......
as for etiquite, thats when ya dont walk on your golfing partners line on the green right?
but seriously, they have ALOT of work still to do it strikes me....
I figure there is at least half a day dragging that plastic horse back to Seville....
They might need to pour it its own foundation lest it may sink in the mud.

There is still a slope, sort of, in that the lowest point of the entire reservoir is beneath the lift. The water is pumped from there back to the "top", and it travels back down to the lowest point. Filter & repeat.
And no, the water would not spill over. Remember - this is a closed system (well, two separate closed systems). If you shut the pumps down, the water just stops flowing in the same way a treadmill belt stops when you turn it off.
The water level will always strive toward equilibrium, and so long as the walls that contain the water are higher than that level (plus some extra to allow for waves, etc.), there's nothing to worry about. Yes, the water at the outlet of the pumps is a tad bit higher (as the pumped water disrupts that equilibrium), but that "extra" volume is counter-acted by the slightly lower level near the pump inlet, where the water is sucked in.
Brandon
At resting point, the entire volume of the pool must not over fill the banks of the lowest rim....in that the pool is at the "so called" upper end of the system, if it were higher than the end point (where the water is drawn for the pumps) it would tend to over fill the end point of the flume when the pupms were turned off....therefore there can be no slope unless it is so slight that the excess concrette wall is sufficient to contain the upper "head" at rest....
Im suggesting that the entire system was designed as one level water depth such that parts that are above water with pumps on are the same during pumps off and the only head that ever gets built to initiate flow is that created by pumping water from one end of the system to the other.... if I am wrong I would be interested to know as I have though a fair amount about it...
and yes, the water pumped up the hill to facilitate the boat coming down the hill is cosmetic as i suspect a seperate pump draws that from the deep well at the base of the hill and sends it up the pipe just below the track....Tony took my fav pic of the whole ride showing the port where the water line connects to the track a few weeks back(and the bottom view of the gear mechanism....)
in this way, any transient pump flows are minimized with the already existing head.

You are correct. Most flume rides do not need water to make the drop. The boat can drop on its own without needing water except at the bottom to slow it down. And actually some water rides still don't need water at the bottom for the boat to drop. As long as the run out is long enough, a boat will eventually slow down enough. While this is not something to do with guests on board, it can be done.
^Hey! I believe Your_mom_is_too_fat_to_ride_TTD. is 16. He's the youngin' on here, with me being the second youngest (17). Thats out of those with listed birthdays though... :)
I really do like the progress though. Anyone else notice the white hose running from the ground up to the top of the first drop? I'm guessing that's where the water will be coming from, but heck, what do I know?
I'm really looking forward to riding the ride, and trying to find this "edit" button you guys are talking about. It must be around here somewhere... :)
EDIT, 10:51 PM: Found it! :)

The slope (or, more accurately, the "delta H" (which is the difference in height between the pool/pump outlet and the bottom of the lift base reservoir/pump inlet)) has absolutely no bearing on anything regarding wall height; So long as the the walls are high enough to contain the entire volume of water (plus allowance for the "head", waves, etc.), there will never be any overflow.
I think we're describing the same phenomena in different ways. Using sentences, grammar and the like might help convey your thoughts more effectively. :)

I'm so lost. Were there posts deleted? Some things people are talking about aren't on here. I'm guessing something happened.
Let's Get Weird.
@Youngin': Yea, a few off-topic ones were deleted, and a few were merged.
Didn't Tony say he'll be in Virginia this week @ KD for the I305 Preview? Probably, so I'm guessing no updates this week. :(
Maybe Tony will give us a photo update and/or Pointcast on the road like they did last year for Kings Island and Diamondback.

You mean a construction update? Both Intimidators are finished and I'm fairly sure Demon Drop is done so that would seem pointless (no pun intended). I think the only reason for last years Diamondback episode was due to KI's proximity to CP and how big getting Diamondback was for KI.

I do know that both Intimidators are finished (Carowinds being opened and I305 opening friday). I was just saying since Tony is going to be at Kings Dominion for I305's opening maybe he will do a video/photos as he did with Diamondback.

I wouldn't count on it. The big difference here is that Diamondback was work related and 305/KD is purely leisure.:)
(though I don't mind being proven wrong;))
