wwg not sure what are asking I would not drain it down for the purpose of stocking bass. Manage it right and your bass will grow. The F1's are mostly sold as fingerlings so survivial is pot luck with existing bass. Nick has a very good point if about the Florida's breeding with your pure Northerns (if that is what they are). As mentioned F1 is the first cross. After that there will be a mix of genetics. IN theory you should after the first spawn of F1's have 25 % pure Floridas, 25% pure Northerns and 50% F2 crosses.
