You may go another mile and find the same situation and catch some more. You are then on your way to a very successful day. This is one thing I really do not like about fishing tournaments on a river. Unfortunately, all the good spots are easy to recognize. Fishing tidal current is really no different except timing is extremely critical.
Tidal fish move a lot but are very predictable.
If you catch them off a spot, pay attention to the time and tidal level. Pay lots of attention when you catch tide-water bass and get a tide chart. Catching these bass can become very easy if you get your timing down on all the spots you locate. Some spots will be good on high tide, some on low tide, and others at certain stages in between. It's your job to determine when a spot is best and then duplicate your timing on it in the future.
