AskHouston: connected waterways

Hi all, neighbor from Dallas here. I'm wondering if any of your area lakes are connected to one another through a passable waterway?

I'm thinking of planning a trip next summer where I'd be going from one body of water to another on jetskis.

Just looking at maps I'm seeing the the Trinity River from Lake Livingston to Trinity Bay, is that passable by watercraft?

Or San Jacinto River connect from Lake Houston to Bear Lake. I'm guessing from Bear Lake to Galveston Bay would be connected.

Thank you for any help or pointers on finding out this information.
