Can you send me the link?

that's what I hear from a lot of folks.....but, quite frankly, I just don't know and I never have kept a diary of my trips.....even if I knew, I would never let BP stop me from going.....I just enjoy being out there.....something about seeing that cork go down.....

Absolutely

I'm thinking that barometer is a hard one to figure. I inherited one last July and have been watching it close. I had good trips around 30.4 which some say is too high. It's confusing on a nation wide forum when folks talk numbers that vary so much with altitude. Lafayette is 30.15 now Box Elder Montana has 27.05. That would be a bad storm here. I think it's just one of many factors and doubt if any number will keep me home if other things say go.

Water temp is another thing I don't worry about. My Humminbird just gives the surface and who knows what it is down where the fish are holding. It's just me, but I never look at that on my Hummer.

You know the trip right after new year I took in pigeon, I was documenting the weather in a fishing journal I started last week...I looked up a weather archive on one of Baton Rouge's news network websites. I couldn't buy a bite in the morning but I found em in a canal and did well after 1030 till about 130. I noticed on the weather archive a stark drop in the pressure at precisely 11:00 till 1:00 in Baton Rouge...so scientifically its impossible to say if I found the right area, or if the fish just went crazy for 2 hrs...or the more probable theory - a little of both...In my mind pressure definitely affects them....

I have often wondered about such things. When I apply the math to it I think in terms of this:

1" Hg @ 32°F is 0.49 psi of atmospheric pressure difference

With a freshwater hydrostatic column at 3 ft., a fish experiences roughly 1.3 psi
If said fish moved to 12 ft., the pressure would be 5.2 psi

So, it appears to me, that atmospheric pressure has little do with how the fish feels, they would just move in the column of water that suits them. I am no biologist, so have no idea.

Randy,
I never thought of the severe pressure gradient in the water column as compared to the air pressure...you just blew my mind...POOF!

Yes GF, I remember. I also remember you not PMing which canal it was.
