Big Lake - Fall up north?

[ahlangle]

Heading to Big Lake this week and have not fished the area in the fall like this ever.
Have been doing some homework and thinking about going further north than the lake.
Any general info on when the fish move due to the cooler weather, what the thought process is behind shallower water, marsh in the cooler weather, tides' effects on the water and subsequently the fish further north, etc?

Anything helps, I'll post report after the trip.

Thanks guys,
