I'm always tinkering with something.
One thing I'm always messing with is the spot where the water returns from the bog to the pond. I mess with the way it looks or the way it flows.
It's only a few steps of flat stones. Not much of a waterfall.
I'll add a flat stone, or maybe take one flat stone out. Or I'll mess with the bog gravel near that spot.
Doing any of those things can raise or lower the water level of the bog. It doesn't take much to make a subtle difference.
I can go from no water above the gravel to a couple inches of water.
Sort of fine tuning the water level of the bog.
And here's the kicker, which should be obvious, but I never really thought about it...
If you raise the water level of the bog, you lower the lower the water level of your pond (or visa versa).
I was going to add water to my pond because of this, then it rained and it's now completely full.
Thank you Mother Nature!
