Half fill the swimming pool with water.

The swimming pool overflowed and caused the water level to decrease to half or by half?
I don't see how the amount of water in a pool can decrease if the pool is overflowing.

Could it mean that it overflowed and half the water went to waste... (That would mean that 'the water' meant something other than the contents of the pool).

Thanks for replying.I just wanted to construct sentences by using the word decrease, therefore I chose swimming pool.How about if I construct a new sentence? He jumped into the bathtub and cause the water to overflowed and the water level to decreased by/to half. Is the above sentence correct?

... He jumped into the bathtub and caused* the water to overflowed and the water level to decreased by/to[Either! - it amounts to the same; depends whether you're a 'pool half full' or 'pool half empty' sort of guy. But 'by' is more likely] half. Is the above sentence correct?
