Wish I could be helpful........but, worked all around the Dallas area, but never fished
any of the waters in that area. Since I retired, I can't find a reason to ever go back
to that area. Lake Lavon hold lots of crappie. Joe Pool holds lots of crappie & bass,
but I haven't fished either in over 15 years. Unaware of any fishin' barges, but that
ain't sayin' much. Hope someone can answer your questions and help your son find
a place to take his family.
