I came home this morning from a trip out of town to find that approximately
1/2 of the water in my 3,000 gallon pond had drained out. Not going to
bother you with all of the particulars snip

Here's my question: Does the 10% rule hold in the winter and, if so, how
long before adding the next 10%? TIA John

As long as you have sufficient water treatment for chlorine or chloramines
you can refill..... though I'd do it at a slow rate over the course of a
day. Now if your source water is 10 degrees different in temperature with a
0.4 difference in pH. You might want to let it trickle in over 2-3 days.

Unless it gets below freezing, in which case your hose may freeze. And I agree
about the pH. Be careful there. It would be good to test the pH of the pond
water and that of the water you plan to introduce to make sure that there is a
huge difference.

A couple of weeks ago we had a lot of rains over several days (probably 5 inches
total) here where I live. The water got within an inch of the top of the pond.
I connected my diverter hose to the hose that goes to my waterfall, and closed
the valve to the falls. Then let the water run out onto the patio. I went back
inside because it was about 29 degrees F outside. I then forgot about it.
Oops. Fortunately, my punp system is a suction system that cannot pump more
than about 1/3 of the water out. Still, I was quite mad at myself for the
situation. The pond water at that time was about 45 F while the water coming
out of the faucet was about 55 F. I used the appropriate amount of dechlor, and
turned the water hose on about 1/3 of the way. It filled back up within about 1
1/2 hours. Since then, I haven't had any problems. All of the fish are fine.
