Tide ?
 

Assuming low tide at the jetties is 8am, what would the time differential be for midlake and the most northern part of the lake(big lake)?

i would like to know this as well.

check out the history on the buoy at the jetties and at hackberry. It will show the time differences.

I would say 3-4 hours from the pass to the long point area....go to tides and currents and check them at the jetties compared to hackberrry and L.C.....

That was the web site i meant.....also tides and currents/noaa is good to.

I have no clue how to interpret those W drawrings for times. Got anything a redneck can understand?

Try this one...
 

This link is really great, gives you everything in real time, i use the bulk terminal for a gauge for Turners.

Depends on tide speed... It can take one hour or 3 to 4.... Also wind affects the tide...right now with full moon it will not take long to start moving water from south to north.... Moon controls you tide speed...

From jetties to south end 2 hours. 4 hours to north end.

The time differental is also dependent on amount of tidal change. When there is a big change [2 foot] then you will see the water movement a little sooner.

If the tide change is less than 1 foot..... it takes longer to see any movement.

Also wind is a BIG factor to consider.

If you get really inspired you can download the data from the NOAA and USGS site in tabular form and compare the actual river levels versus the predicted tide tables. I did that a while back and came to the same conclusions as "W", there is a lot of variation and it didn't directly correlate to the wind speed and direction although I know the wind plays a big factor. If you really want to confuse yourself consider this: When the tide is high you would logically think that the current would be slack and when you are half way between tides you should have maximum current because that is when the levels are changing most rapidly. True for some river systems but not so for the Calcasieu I was informed by the hydrological scientist at USGS. For the Calcasieu, the tide and the current max at the same time at least at the Cameron Lighthouse but there is usually even a little lag there from the predicted tide tables.

That was a general rule but it's not going to be far off one way or the other. Or you could just do what I do, fish daylight to dark
