Well I was originally getting alot of splash. I ran 2 inch PVC to the
top of the falls, that at first, was simply spewing out into a 6-8"
deep holding pond. The first night we ran the falls we woke up the next
morning to a nearly empty pond. Were talking 1540 galloins of water
almost gone. I since have fixed the outflow pipe so that it fills the
holding pond from under the water surface. Rather than pouring out and
splashing/churning, The water now just rises around the pipe and spills
over the lip of the holding pond. No splashing. There is one spot where
the water tends to trickle out a little when it runs through the stream
connecting the holding pond to the "falls" . Its noticable, but not
enough to lose an inch of water an hour. Will remedy that soon. I do
have a couple semi-large rocks in the stream in order to direct the
water flow where I want it. It does splash against these 2 rocks but
not much and i have them positioned so no water splashes out over the
edge of the pond. Or at least not much. Also, the falls come down a
stream that is about a foot wide, and then the water spreads out over a
large area. More like water cascading/sheeting over the face of the
falls rather than simply dropping from a ledge into the pond. I have a
feeling this is causing alot of evaporation. Spreading all that water
out so thin over such a large area cant be good. I inherited this pond
and it just wasnt built to have a single "thick" water fall. Like I
said, its a very thin sheet of water sheeting over the face of the
falls. In the stream the water is pretty deep and flows like a river
more so than a stream.
