Taylor,
This is not going to be easy with just one person. You need a buddy to help you and seine it. Other ways on your own?? A large mesh net maybe? Maybe drain it even more if your going to move the fish and then get in there with a large net you can handle on your own? I am quite new to this site so maybe some of the other vet's here may be able to give you a better answer. It really isn't a one man job though. You might want to use a little bit of water from the well just to keep things going till it rains??? Good Luck I am sure someone else may have some ideas as well.
