I've never heard of Ryan Creek, but two areas are always of interest for me in a kayak on/near a big lake.

1) Feeder creeks. Best ones are always at least 8 to 10 feet deep with laydowns. I look for creeks that have something to block big boat traffic much of the time. Limestone with the winter drawdown causes the low water at the mouth. 8 Mile creek is blocked by the county road. These features limit angler traffic, but not fish movement.

2) I love finding borrow pits behind or adjacent lakes (typically near the dam). No one drives miles to big water just to fish the 10- or 15-acre borrow pit behind the dam. Many borrow pits only connect to the lake or river during high water and aren't accessible by road but are on public land. If they don't go dry in the summer, they can be epic!
