There is great variability with depth to the point that some current tables will give data for current speeds at depths below the surface. This is very similar to the wave created by sloshing water in a bathtub. [See example here (jpg)] The exact relationship between the times of high and low tides and the maximum current or slack water is unique to each location and cannot be determined from a generic "rule of thumb". When survey leveled from these markers to the tide station, the relationship calculations for these marks must match within 9 millimeters.

If high winds are steady for a long period (e.g. The current then begins to slow again, heading toward the next slack, and this deceleration also takes about three hours. Slack water occurs when the incoming current due to the tide change cancells the outgoing current coming from the rivers and streams.
