Noles,
Other than LMB what else is in the lake?
A gill net with openings too small for larger bass would prob. do it but there may be better/easier ways.
I assume you are in the south. location will make a difference in recommendations.
The seining idea is not a bad one if there is a suitable area.
Ask your state wildlife comm. if they have any ideas.
The National Wild Turkey Fed.
http://www.nwtf.org/ holds kids (jakes) and women (women in the outdoors) events which may be of intrest. Talk to your local NWTF chapter. The events are very well managed with fishing a big hit with the kids & women. You will have control over what they take out of your lake.
