Might be best to wait until water table under the pool has gone down to prevent the pool from popping up out of the ground. Believe me I've seen this happen. The only thing keeping the pool in the ground right now might be the dirty water inside it.
Once the flood waters subside and the water table is lower, then drain the pool, clean the inside with acid wash or chlorine, and purge the flood water from the underground plumbing. Depending on your filter you may need to get a new filter and/or cartridge/sand when you get the new pump. Flood water that has made it to the inside of a filter seems to never get cleaned out and will cause problems for a long time. If you ever thought about changing the filtration layout now might be the time.
My family and I are praying for a speedy recovery for every one impacted by the flooding. God bless.
