On the upper end, the channel will be about a foot lower than outside the channel that is 3-4 feet deep.When you get down towards the middle of the pond the channel is 3-4 feet deeper then outside. The top of the channel will be about 5-6 feet deep.

I am going to place some Porcupine Fish Attractors and PVC trees right along the drop off and maybe place some cedars in the channel on the upper end.
