There is a parking lot at Highland Lakes park that you can portage your kayak from.
The city permanently dropped the water level of that pond by about six feet when they started the updated bridge construction seven years ago, and the fishing has suffered since. The best areas are along the rip rap and under the I-35 bridge. There used to be a pipe/culvert that connected the pond with Lake Lewisville--not sure if they kept it open.
CCTX is spot on, use to be a fun close to home kayak spot. Never caught anything of size but would catch plenty in the 12”-16” range. Since the construction its fishing has been slow for years. With that said I still fish it and just have no expectations of catching.
