I checked out three places yesterday.
Denton, South Lakes Park. The lakes look great with several folks fishing the main lake on the northwest end closest to the parking lot. It's a hike from the parking lot to the bank.
Lewisville, Railroad Park. This is a huge very nice sports complex with a nice lake on the far east side. Once you find your way to the east side of the parking lot, you can park very close to a nice floating pier that looks pretty fishy. This is a newer lake with no real structure or grass in it so fishing might be spotty, all put and take. It is stocked with keeper size cats I hear. No one was fishing.
LL, the fishing barge. Nice big barge on a steep bank with close parking on a dirt lot. Folks were fishing it and it looks to have deep water under it. $8.00 for adult with one pole. Bait is available on site. It looks pretty fishy. FM 407 takes you right by the barge.
