Could anyone help in providing their knowledge of any creeks or tributaries that tend to feed lake Fork with relatively clear water run off?
Most of the dozens of coves, inlets, and lake arms on Fork ultimately have runoff of some kind rather the runoff be a small drain a large creek or anything in between...

Just look for the fleet of boats out there and that should answer your question. Especially this weekend. I've wondered the same thing

Look for the coves surrounded by houses with large yards... All the grass keeps the runoff clear.
The others have mud banks or weeds along bank are muddy.

If you're fishing tomorrow morning......... good luck

Look for smaller creeks, pockets off the main lake. Creek channels that the mouth faces the south-southeast tend to get less wind early spring and will be clearer. Mid to south part of the lake will be clearer as a general rule as well.
