I have a pond & waterfall, here is a picture. Not a good picture because you can't really see the pond, but where the little wooden bridge is, that's where the water is.

The dark rocks above it is the waterfall, we just run a hose from one corner up to the top, and a pump moves the water through.

We don't have any fish, the pond freezes solid up here in the winter. At night, the area is lit nicely with landscape lighting, and we put a light in the water and another highlighting the courses in the waterfall.

I haven't put plants in it for a few years - some plants (water hyacinth and water lettuce in particular) take over, and this pond isn't too big - it's about 180 gallons or so. Plus the bridge covers a lot of the surface, so I just leave it water.

It is very relaxing to sit by the pond and listen to the water running. My 3 dogs never bother it (but you might be able to see some dog spots in the lawn - ).

I used to have it fenced off from the dogs, and it had no grass - it was surrounded by plants, but we took out the fence and put sod in last year, for a simpler look.

It is some work, but we have a filter (it has a name - but I forgot what kind of filter it is) and the pump keeps stuff moving.

Lots of urban wildlife come in and drink - squirrels, rabbits, raccoons (I never see the coons, but the neighbor says they come in at 4 AM usually), chipmunks, birds. Our yard is fenced for the dogs, otherwise we'd probably get deer drinking from it too.
