Make sure the delivery pipe from the pond pump is not kinked or is being restricted by a build up of algae inside the pipe. This happen quickly in transparent tubing exposed to sunlight.

To determine an approximate average depth of your gold fish or koi pond whose depth is not constant take a stick and mark it in intervals of say 3 inches with an indelible ink pen. At 10 different places in the pond insert the stick and record the depths (10 numbers). Add the numbers together and divide by 10. Use this answer as the average depth of the pond.

If your pond is of equal depth and the same cross section then you can very accurately measure the pond volume as follows. Measure the depth using a tape or stick. Using the pond pump measure how long it takes to fill say a 5 gallons container. Now pump water out of the pond for say 5 minutes Record the depth after pumping out water The pond's volume is then calculated as follows:

S = depth of pond in inches or any unit before pumping starts
D = inches or any unit of water pumped out of pond when pumping stops
T1 = time to fill the container
T2 = time pump was run to pump out water
V = volume of container
Volume of pond = (S x V x T2) DIVIDED BY (D x T1)
If container was in gallons then final pond volume is in gallons. If container was in litres then final pond volume is in litres.
It does not matter whether you measure pond depth in inches or any other units.
