This first photo is the entrance to the channel

This second photo is about halfway up the channel. At sometime in the past the concrete wall was notched to facilitate fish passage through the channel.

This photo is looking upstream to the pond from where the photo above was taken. The pond is in the background just beyond the footbridge.

This last photo is looking in the opposite direction of the photo above. It is looking downstream to the notched concrete from the bridge in the photo above.
