In the absence of rec.waterfalls I thought you guys might be able
to help me and my apologies for not wanting a pond ..... well that's
not entirely true, I would like a pond but there are a number of
obstacles in the way to getting one:

The number 1 obstacle is my hubby who will not let me have one. He
thinks I'm the dumbest wife, wanting even just a waterfall beneath a
black walnut tree with another tree close by (our only available
site).... maybe I am dumb, but he's agreed to the waterfall so long as
I do the clean up. I have suggested a net under both trees in order to
get approval for the pond, but apparently I was pushing it However
even with a net, the number 2 obstacles are two large, water-loving
dogs who would simply use it as a large drinking bowl and for paddling
in (putting them - or the husband - up for adoption is not a viable
alternative).

So ...... I have a small corner of the yard where the earth is built
up and I'd like to have a waterfall that is about 3-4 ft high. The
water will flow down for approximately 8 feet and disappear under a
bridge that will be covering a 'holding tank' (I'm not sure what else
to call it, but it's in place of a pond). The intent is then to have a
dry river bed of rocks to imitate a stream coming out from the other
side of the bridge. This will go along with the theme we have running
in the yard - a sort of japanesey feel to it. My husband had a notion
that he liked bamboo and bought one plant. Two years on, we now have
it everywhere .... tall, short, thick, thin, rare, common, running,
clumping, yellow, black, striped - and all expensive and labor
intensive to put in. But I digress .........

My first question is about the holding tank - does anyone have an idea
(assuming my conveyance of the overall picture is sufficient) how big
this tub should be? I was thinking of sinking a tub liner for a half
barrel that you can buy at Home Depot (no idea how many gallons they
hold), but will this be big enough? Alternatively, I realize I could
just dig a hole and put pond liner in, but again ... how big a hole
should I dig?

Second question: is 20 mil pvc liner okay, or should I go for the epdm
liner to line the water fall?

Third question: I've been looking at pumps and have figured that I
don't need anything too powerful, however I'm not quite clear on the
pipe - should it be 1/2", 3/4", more? Or is this governed by the pump?

Thanks for any suggestions - valuable or otherwise - that you may
have.
Jane

p.s. Work starts tomorrow morning after my husband has slept late, had
two coffees, breakfast and messed about on his computer for several
hours ....... oh, and after we have visited the place where we're
going to buy rocks - evidently my penchant for wild colors is not to
be trusted when choosing rocks.
