Get a map. If you see a low depression, that is where the water is. Bring the total amount of water you will need for the entire trip. The water source you find may be bad. You'll need water clearification equipment or pills, then you need to boil it.
There aren't enough good heavyweights to have a 230 pound division. You would basically split a small number of good athletes in half. Can't have too many weight classes as it will dilute the talent as happened in boxing. I'd reorganize as follows:
130- WEC BW
140- WEC FW
150- LW
165- WW...
