Tami,
Throw a few willow branches in with the koi and then you'll really have some great water.
My basement looks like your yard - or did a few days ago. Have had a crew of 5 guys here for what seems like forever as they manage to handle all my stuff with their retched, twisted, needy little claws. Oh well, at least it's dry inside again. Of course it's raining outside and that includes decent size (as in big enough to hurt) hail stones.
It's always something aint it?. Other then the water your place looks nice.
