Hey guys I was just having a talk with dad and we were talking about how effective a green pumpkin trick worm is 15-20ft deep (deep for most lakes around me) if on the surface you only have 2-3 ft of visibility? I know fish can see much better underwater than we can, but do you think that deep in that dirty of water green pumpkin on a bait that does not put out lots of vibration is an effective color?

If you can see 2-3 feet then a bass sees about double that distance.  The silhouette of the bait is still there and the vibration is still there.  A bass' lateral line can pick up the slightest movement in water. 

Yes, Ive fished Red and Green pumpkin in water with 5 inches of visibility (yes that is possible) and it worked fine. Maybe not the best choice but the bass can certainly see the silhouette of the bait and pick up the vibrations very well.

2-3 feet of visibility is pretty average for a lot of lakes I fish and green pumpkin is one of my favorite colors. 

Two to three inches of visibility would be dirty water. With two to three feet, fish can see well enough you don't have to hit them in the face to get their attention. Green pumpkin is good, PB& J is better.

I've caught fish in dirty water on a Green Pumpkin Red Trick Worm dipped in Chartreuse JJ's.
