A number of times a year (or a month) about half the water in the pond "goes

How big is the pond? What kind of waterfall/stream?

At the demo pond, due to the style of water fall, if a strong wind comes up
we can lose a lot of water as the wind blows the waterfall sideways.
Perhaps that could be happening to you? ~ jan
