The pond I'm designing will eventually accept roof drainage (directly into the pond, through a pre-filter, no storage system). About 600sf of roof in the PacNW. I've been casually calculating expected evaporation and precipitation to figure out how much freeboard—how much holding capacity above normal water level—to leave myself to account for rises from rainfall before overflowing to a dry well that I have downslope of the pond.
Wondering if any of you thought much about this before digging and how you decided what to do about it.
I don't care for the aesthetic of a big berm around my pond, and I think I've come to a happy compromise for how I'll handle it, but I'd like to know how you approached it.
I think the main issue I'm going to have from draining my roof into the pond will be that I'll get tons of water when I least need it, and very little when I do. But I think that's a limitation that can't really be worked around without some sort of "out of pond" rain exchange / storage system that I don't have the desire to figure out right now.
