Welcome to the forum! Glad to see you getting the kids involved! They are the future of our sport.
I'm not familiar with that lake, but perhaps someone who is will pipe up and give you some tips. I'm pretty sure that the primary forage for striped bass in that lake is shad.
I'd also give Atchley's a call and see what they have to say
