I wouldn't worry about the timber. Look for the other structure like points, creek channels, brush piles, grass lines. Fish patterns. If there is timber around other structure your fishing then give it a few casts. But I wouldn't focus on timber on Fork. Its everywhere you go. From my limited experience on lakes with a lot of timber the fish will follow similar patterns as other lakes without it.
If it ain't yours don't mess with it!
