I'm curious, what is the minimum for your state and is that lake's min. different than the state minumum? 14 inches is a nice fish - not big but nice. Is the lake fished very hard? I've caught a lot of similar sized bass. There are alot of variables out there on the waters we fish. For me I've had to trust my sonar more and explore away from the shore to catch bigger fish. Our State min. is 12 in. on rivers and 14 in. on lakes but I fish one lake that has an 18 in. minimum. I've only caught 1 legal fish on that lake so far but I also had one of my best days fishing there. Do you adjust tactics with the fish - that is so hard for me. Finding the fish; finding what they want.
If the fish are not getting any bigger than 14 in. you should see signs of it in the ones you are catching - signs of stunted growth.
Has the DNR done any surveys on that lake, if so what did they find?
One thing in your favor if you have fished it very hard for the last 4 years and explored it, you probably know that water better than most out there.
What I've done is try to find good fisherman and pick their minds and try to understand why they do what they do, then hit the water.
Hey - stay legal, look at your tactics, look at other area lakes - you may need to change or add something. Regards, BT
