    Hello,
    I'm researching building a pondless waterfall and ran across a website that gave these estimates for a "Micro pondless waterfall":

    "Estimated quantity of stone needed:

    6 inch to 24 inch boulders - 4½ tons (waterfall and stream)

    4 inch to 6 inch boulders - ½ ton (cover the centipede unit)

    1½ inch to 2 inch gravel - 1 ton (tops the 4 to 6 inch layer)

    ½ inch to ¾ inch gravel - ½ ton (Top off the basin area) "

    Does that seem in the ballpark? The 4 1/2 tons of boulders is what seems high to me, also a total of 2 tons of various sizes for the basin area??

    The info was here: http://www.pond-pump-and-fountain-supply.com/micropondless-waterfall-kit.htm

    Although I wouldn't purchase the kit, I like the idea of the lower cost alternatives to the centipede module and snorkel vault.

    Thanks,
    George

    the amount of stone you need is determined by the length of the stream. also how you construct the bottom pit to collect water.

    this would be for a small stream, 10' max.

    for a 10' stream I would start with a ton of boulders, 1/2 ton of 1-3"s. if you have to really disguise the box at the top then order another 1/2 ton or so of boulders.

    That's a hunk of rock for a "micro"... the attached image is more my idea of a micro:

    That was about 1.5 tons total.

    Your rock list fits my description of a small to mid-size pondless.
