Can't add much to what EB has said already. There are things you learn thru the years that you just pick up. One of instance is if you have been catching crappie for a few days at a certain depth (lets say 5') and a LP or cold front moves in and chases your fish from the bank. Where will you look for them??? I can tell you from experience that those fish will move off the banks but they will mostly still stay in the 5' to 7' DOW but will stage in deeper water.
On Tenkiller during all seasons the fish relate to wood. Either man made wood piles or natural wood. Standing trees in the winter when it gets really cold and the ice freezes in your line guides. Not saying you can't catch fish on anything except wood but most fish in clear water will relate to something like wood on Tenkiller.
This time of year during pre spawn crappie are on the move. They are headed for those spots on the lake that are magnets for spawning fish. There are so many of them its hard to say were to start. I can say the far South and far North part of the lake warm faster than the middle of Eufaula. Its the same as far as Tenkiller orFt Gibson is concerned its the shallower portion of the lakes. Its the dirtier water that warmsfirst. Its always the North banks since the sun is in the southern hemispere that gets the most sun to warm the water. Winter like EB said its the channel and the breaks on that channel that needs you concentration. Now til full blown spawn its the slowly sloping or flats between the channel and the spawning banks that you should be targeting. Just a few degrees of water temp in the right direction will push those fish either closer or farther from the bank. Usually when you think your fishing slow enough this time of year you need to slow down alittle more. Good Luck...Ranger
