Toledo bend Boat lanes

I remember last time I fished at TB I spent a bit of time trying to navigate the boat lanes via printed map. Does anyone know where (if possible) to get the GPS file for boat lanes for free on Lowrance elite 7 series? Maybe purchase is the only way. I'm going to give it a shot on Saturday.

thanks in advance.

I have the Navionics card in my chartplotter which I use. The Navionics app for the phone is very good as well.
