We feel the pain Daniel. We have to start in a month getting ours cleaned out and re-sealed. Least we don’t have to use a truck or a Jeep to get out the plants ( We hope they are still in 5 gal buckets. Our take about two day to get our pond drained to see the bottom of all the crap that is settled there.
Photo shows a few of the Koi’s cumming up from the bottom of the 3 to 4 foot pond and looks like a few more baby’s.

Most in the pond is around 2 to 3 foot long and been in there for over 30 years or more.
Anyway… we feel for ya and it a messy job.
We don’t have that many fish, but the concrete pond is cracked, due to improper construction by the original owner, so we are just going to line it. At the same time, we’re potting the lilies, and a few of the irises, so we won’t end up with the two-thousand-pound floating iris bed again.
