You guys are smarter than me, so ponder this:
My Turtle Pond is about 4000 gallons which would equate to about 100 gallons per inch as it ranges from about 40-45 inches (sides are straight down, no slope) in depth. Surface area is 150sqft.
So if we get an inch of rain, that would add about 100 gallons to the pond?
In January we got over 10 inches, so about 1000 gallons.
My old home had no gutters, but put them on this one. 1/4 of my roof (say 500sqft) is now being directed to this pond, so that adds at least 250 gallons per inch of rain, probably more.
I believe this would suggest about 3500 gallons of free rain water entered my pond in January.
As all know, the best thing for aquariums and ponds is replacing a percentage of old water with fresh on a regular basis. I don't mean topping off from dehydration, but draining old water and refilling. This reduces nitrate, etc in the water. Rainfall is one reason outdoor ponds are much easier to maintian than aquariums.
Average monthly rainfall in my yard is around 4.5 inches, no matter the month. Some months we get more, some less. An average input of free rain water should be about 450 gallons every month. Adding the roof water adds at least another 1000.
So roughly, is 1500+ gallons of free water a month a good guess?
