Eldridge has the times and directions of the current changes. It tells you the direction, time of change and maximum velocity of flood and ebb for a particular day. ( not factoring in rainfall or other weather events)
Currents directions are always given in True.
Hell's gate ( east river) floods East or toward LIS and Ebbs West toward the Battery and out through the Verazzano. ( The Narrows)
Cape May inlet ..would Flood West...and Ebb east. The times are listed in the front of the eldridge book and are based on the Delaware Bay entrance. either + or - time..
Chesapeake City...would flood toward the Chesapeake bay. and ebb toward the mouth of the Delaware bay....The C and D Canal has it's own tables in eldridge.
So you would go to the particular spot you're interested in knowing the time of the current changes...see what major point the timing is based on and either add or subtract the time given in the current stations.
Eldridge will give you time of current turn, and the maximum velocity of flood and ebb for that day.
Eldridge is essential equipment on my vessel on the east coast. I know that there are many ways of obtaining this information, but I like having the book in my hand even if it's to check what my Plotter and handheld is telling me.
