Welcome to the forum. If you're adding 100 (or even 1,000) gallons a day, it probably won't do much for the pond. In one study that I read, evaporation rates (yearly) varied between 51 and 68 inches per year. A half acre pond, at full pool, loosing 1" of water looses 13,577 gallons of water.
Regarding the fish, it all depends on what your goals are for the pond. If you want a more balanced fishery with feed trained fish, then:
If the LMB in the pond aren't feed trained, I'd suggest catching and removing every LMB, no matter what size, for a year. Make a concentrated effort on fishing for LMB at every opportunity. Then contact Greg Grimes at
http://lakework.com/site/ for feed trained LMB. The large CC are eating a lot of fish, both small CC and BG. Remove as many of the large CC as you can and restock the same number of 9"-12" CC if you want CC in you pond.
If you want to concentrate on large BG, then leave the LMB alone, and start removing female BG. Feed them, they'll learn. The LMB will concentrate on the baby BG, leaving more food available for the larger BG.
Water color or rather clarity should be around 18", but anywhere between 12" to 36" will do, providing that the clarity is governed by phytoplankton rather than clay turbidity. There was a great article in the PB magazine a couple months ago on water quality. Call the office and order the back issues.
