THUMBS UP
@YShahar great minds think alike. i had the same using that same area as a planter and sitting area. sitting on the steps will leave you wishing you had somewhere to leave a bench or nice comfy chairs set up and not have to pull them in and out,
Your falls are all at the edges or narrowest parts of the pond . the splash from the falls will be a loss of water and require constant replenishing.
Like i had said before if i had to do it over again i'd make the pond narrower and longer. but that can require seeming but seeing as your driveway is right there it's easy beans.
Ok this drawing is a bit of a mess but it's just for thought.
1 the blue pond
2> green bog
3 pink spill bowl
4 bog can be any shape you'd like by making it a bowl and pulling the falls inward can help with that and widen the area
5 the yellow would be liner as it wraps up the wall of the bog and around the pond and i would make it go under the spill way bowl.
6 black in the bog liner over laping the pond liner brown is the outer edge of the bog
7 ran out of pic for the intake bay i would make that at the upper right and maybe have it point diagonal kinda like under the pile of rock
8 i would also put a return jet in the far opposite end of the pond closest to the stairs pushing the water out of that corner
