Pump to bail out pond water

A question about : Pump to bail out pond water

We have two patio ponds (above ground). No filters etc. When it rains excessively, we need to watch to water doesn't reach the rim, simply to ensure fish don't go over. If the level gets a bit high, we manually bucket some out. I think I'd like some sort of manual pump that would allow me to bail water out. Does anyone know of such things please?

Best answers:

• Traditional water pumps are available.

  Could you build in a weir rim to part of the pond, with a grille to hold back the fish?
  An electric dirty water submersible pump with a float switch at appropriate level would probably be cheaper (and automatic, and less work)
• Far too expensive for the occasional use.
  I would be thinking one of theses and a suitable length of hose.

• As you say the ponds are above ground, so the water level of wherever you are bailing to is lower, wouldn't a simple tube as a syphon work? https://www.transtools.co.uk/accessor...on-pump-1200mm
• Thanks. Oddly enough, we have a cast iron pump as a garden feature. Because the pump would only be used rarely, a simple up and over type as in last post would be adequate and yes, as a MSE person, quite suitable.
• a submerible pump? switch it on and job done in seconds to a minute or two.
  Got a cheap one from lidl some time back (from a mse post). Works great.
• Fish in a pond and no filters... OH DEAR....
