Good suggestions RAH....Thanks. The 2" pipe does partially clog often but it does give me a reason to walk up the path beside the creek and check things out occasionally. Right now the outflow end of the pipe is about 2-1/2 feet above the water surface so I am getting some additional aeration. I do like the idea of upturning the discharge end to increase this even more.

Seeing the wide variety of what can be done to create habitat structure, I have a lot of surplus scrap material that was left on the property I can use in the pond. Lots of rock & stone, rigid and flex PVC pipe & fittings, plastic landscape netting and an infinite supply of tree branches. The only thing I need to be careful of is to not create something that will look like a junk pile since the water can be very clear at certain times of the year and isn't very deep.

I will post some photos in the next few days.
