I just got a kayak just last week never thought about trying to paddle in from the lake where would you put in from? I may have to try that sometime. Let me know if you want someone to join you. Hopefully we get some rain this year during the fall and winter.
I don't really know, I haven't bought a kayak yet. I'm planning to go to the Second Saturday thing at White Rock Lake this month where they let you try out kayaks for free in exchange for helping clean up the area in the kayak. After that, I think I'll have a better idea of the size and type I'll buy.
If the lake would ever fill back up, you could park and put in on the Garland side of Rowlett Rd. There's a parking lot and a boat ramp. You'd just paddle next to the bridge a bit, and you'd be in the creek. Right now that's just a bunch of mud and grass. So I guess my plan depends on a lot of rain. If there's a good access point off 190, that might work since it's not too terribly far across that part of the lake. It still has water to my knowledge.
I'm just looking at Google Maps, and I'm thinking the distances I'd have to cover without significant rainfall might push me towards a longer thinner kayak.
