I picked up fly fishing a little later in life, but itís about the only kind of fishing I do these days. I live in southern Brazoria county on a private freshwater lake, but fly fish the public saltwater around here quite a bit mainly from a stand up kayak or a friendís center console. But I will wade the surf at times and have a few spots Iíve shore fished that I will list. Many People still think of fly fishing as mainly about cold water trout, but really any fish that routinely take lures and some that donít will take a fly, thatís been my experience.
First, you might look at Tom Bass park close to Pearland (Beltway and 288). I never have been there, but know there is a good sized lake and the shoreline looks clear enough to cast, at least from Google Earth. Bass pro has a pond. Virtually every development these days has a pond or two. It might take a little scouting to see which are accessible and candidates for fly casting/fishing. Thereís the concrete bayous of Houston. Carping, sight casting, with a fly rod is a big thing there. Thereís a number of public parks along Clear creek near Clear Lake. Not sure if any would be great for casting of fishing, but they might be worth a look.
If you want to come all the way to Freeport, the old river area near the police station and high school has some public shoreline and Iíve fly cast and fished off the bank there. Thereís monster ribbon fish that like to tear up clousers, plus some good trout in there at times. Thereís a pier in the town of Oyster creek on Oyster Creek, Speckled trout and redfish move through there but the pier is often occupied. Thereís a little section on Salt Lake in the BNWR that offers shore fishing, same for Bastrop Bayou at the Bridge by Demi John. Shy pond in Lake Jackson has open space. Technically, your are supposed to be fishing with a juvenile to Fish as an adult there. I doubt anyone would tell you not to fish there in the park portion. I hardly ever see anyone fishing there when I drive by. Thereís a couple of spots on Oyster Creek in lake Jackson but I wouldnít call them easy to learn on as the trees are tight.
Any kind of kayak or canoe will open up a lot more water and thereís some lightweight models out there if lugging 70 or 80 pounds of plastic is an issue. I fish with a heavy WS Commander 140, but the Jackson Kilroy LT looks similar and weighs closer to 50 pounds. There might be even lighter models out there if you ever want to go the kayak route.
