Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations small bass

I have about a 5 acre pond/lake in south central Texas that I'm trying to begin managing. The lake basically consists of a series of ravines and gullies that have been dammed at one side, is about 20-30 feet deep in the deepest areas, and holds much underwater structure such as dead trees, etc. Also, the lake gets deep very fast, save for the ends of the ravines. I catch multitudes of small bass (less than a pound) every time I'm out there, with a rare 3 or 4 pounder mixed in about once a month. I know the lake is old enough to carry trophy bass, but I have tried crankbaits, spinnerbaits, plastics, live minnows, live worms...the works...without catching many big bass. I am an accomplished fisherman, so I know by now that it's not as if the big boys are abundant and I'm not catching them (although there are a few elusive ones). I know a few of the bass I am catching are this year's hatch, but even before they had spawned, the catch was small. How many small bass should I harvest in order to produce a larger number of bigger bass? Also, I do not want to harvest too many small bass so as to reduce the number of bass in the whole lake to a level that is not easily fishable. My mother and sister enjoy fishing out there, and they love the fact that a bass can be caught nearly every cast (at least with live bait), and do not care much about the size. How do I find a healthy balance between having larger bass and still having a lot of bass? I have not fertilized or managed the lake in any way as of yet, and an abundance of moss and underwater weeds is at time a problem, especially for bank fishing. Wow...that was a mouthful. Any help is greatly appreciated. God Bless!
