also tide ?
 

Help reading tides ! If it says 1 ft. high tide or low, at Calcasieu pass at
7:00 am what does that mean for turner's,prien,or lake charles ?When do you fish these areas?

Calcasieu pass lighthouse wharf is near west cove so all that means is your gonna see the tidal movement a lot later up north and 1' is the tidal range the higher the number the harder the tide pulls and wind plays a roll as well if the tide is outgoing with a north wind the north wind will multiply your tide. That's how I was taught now I may be wrong, but it makes sense
