A couple of other suggestions for your holding tank, a plastic "sump" which
should be in the plumbing section; or a rubbermaid stock tank which might be
too close to a pond to meet all of your requirements. If your bridge does
not cover the sump you will need a cover adequate to support the dogs and
any small childern which may be in the area. It will take a certain amount
of water to fill the system, piping, waterfall and stream. If you plan on
running the waterfall intermittantly you will need a sump big enough to
contain this water and still have enough to cover your pump intake. If you
are going to run it continuously, you will still have to have enough extra
to compensate for evaporation and spillage from the waterfall.

When shopping for a pump consider the head, or amount of water pumped at a
given height as well as the amount of electricity consumed. In planning the
placement of the pump consider the ease of access to any screens of filters
which may require maintenance.


another thought I have seen some built like you describe using a heavy expanded metal
cover on the tub and hiding that under river rock or other nice looking
rocks it will hold an adult if he blunders onto it
