I've now gone on my second rock reconnaissance, and man oh man this is a difficult decision(s)! I get the fact that in a best case scenario, I would have a bunch of bolders and rocks on site, then start getting creative with the build. My case is in fact the opposite! I'm literally having to select rocks based on the areas I've dug out thus far. I simply cannot afford to have delivered way more than I'll need.
My largest bolders will likely only be around 3' x 2.5' give or take, perhaps I could grab a couple of larger ones though.
This is the hillside where the main falls will be. I'm now wondering if I don't need to dig out even MORE space for rocks. For reference, here's the approximate dimensions of each of those dug out sections. Remember, this slope is way more than the pics represent, around 70 degrees I'd say.
Height x Width x Depth, in inches:
spillway area 8x31x25 ( planning on using the Aquascape 22" ) Also notice on the 2nd pic, that flanking the area where the spillway will be, I've dug out some areas for larger flanking bolders can sit (so as not to slide down the hill!), and will have a flat top spill rock between them. The blue X's are where I will make the path for the small meandering stream to trickle down. I'm leaning toward starting up top, and having it flow under that tea olive tree limb, then into the basin.
1st dug out are from top - 19x54x30
2nd dug out area - 17x54x37
3rd dug out area - 19x40x40
For instance, I could perhaps take that second section from the top, completely dig down to flat so that that wall is gone, giving me a longer area to make for a stream, pooling, etc., but in doing so, I'd then create a very tall wall to contend with, maybe 5' or so, at least. My total length from top to bottom is only about 22' before the drop to where the basin will be. To me, that fall would be a bit much for such a overall smallish hillside. I also like the idea of having 4 cascades coming down, and maybe one more going into the basin.
At the same time, I'm still concerned that even though I've made those areas larger than when I first started, by the time I get some decent rocks in there, there will little to no pooling area left. Yet another conundrum here is SC! Any and all input and opinions very welcome!!
