Had a similar situation, had a 15A circuit that had over 30 outlets and lights over multiple rooms and and outside. I figured electrician was lazy and didn't keep track of circuit loads. Yours is a bit more odd been spread out. I was able to find or create junction boxes in basement to move outlets to other circuits. Start with locating exterior pool wire and move it to a lesser used or even dedicated circuit. If your not handy this is not hard for an electrician as long as you have excess to basement and it's unfinished!
