Burns Run on the Oklahoma side is probably closest for you. It's near the damn. Big beach that's good for launching/retreiving cats. I used to meet friends over there.
There are a couple of other places on the OK side I landed and they looked good, but I don't know the names for sure. Looking at a map, they appear to be in area of Soldier and Caney Creeks.
I always launched off the north end of Preston Point at the Texas Instruments campground (but you have to be an employee or guest of an employee). It wasn't a very good place for cats, but it had a cove with docks so I made it work.
If you can get a support boat, camping on the islands can be a good time.
And on a windy day, it's a lot like ocean sailing because of the long fetches and big waves. I did launch my 17 more than once off of waves.
Some words of caustion:
- Keep a sharp eye on the weather as it comes up really quick. When the t-storms come through, that lake gets extremely
rough. I had to dive for the closest shelter a couple of times after ignoring the forecast and warning signs.
- It's a very busy lake on nice summer weekends. You'd think it would be hard to miss seeing a Hobie, but I swear that Texoma has more than it's share of moron, head-up-a$$ powerboaters. Been buzzed more than once. Took to carrying a flare gun. Fired it more than once - including at a guy who buzzed me twice.
- It's a big lake. Take lights for your boat. Sooner or later, you will get caught out after dark. Lake patrol has no sense of humor about unlit boats (rightfully so). Plus, you're taking your life into your hands at night if you don't brightly light your boat. I'd probably take a GPS too cause it's easy to get turned around at night.
Bottom line: Great lake for catting. Lots of room, good fetches, good wind. Easy to not get bored as there's tons to explore. Pack a lunch and a cooler. Make a whole day out of it. If you can get a fleet going, you'll have even more fun.
