Gator :

How much will the water have to rise before the 2 parts become one ? If you have one part that is mostly empty of predators and will take several feet + of water to connect I would be temptd to put FH ,Gam. and small 1-2 in. CNBG/RES in it to grow. Enough BG/RES for 1 acre not 8 if you expect the 2 to remain seperate for 90 days. I would also start fishing elsewhere for BG and add the adults you catch to the pond. You could also use your small pond, if it has water to start to grow out any of the forage fish.

Post back what you expect on the water situation and I will try to come up with a plan that considers all you have set out above.
