After the last round of heavy rain we lost a lot of fish due to pipe overflow. We have no added an elbow and filter in order to be able to adjust the level of pond and prevent fish being swept down pipe.

The elbow can be rotated to adjust pond level (to try take advantage of spring fed inlets in drier periods). As water level has started dropping we have turned the elbow upwards and now it appears that spring feed and evaporation are equalized.

The filter consists of 4″ pvc tube and end cap drilled with ¼” holes.

As you can see from the images that water is amazing clear!
