So, anyone not up to speed with tides and currents could legitimately ask how slack in the above post could occur two hours before high tide.

Current and tide are two entirely different animals.
Looking at Dodd narrows, slack occurs when the water level north and south of the narrows equalizes.

Because, in the case of the flood, the north fills from many areas, it equalizes ahead of high tide. The tide then just continues it's overall general rise for another 2 hours.

True slack water occurs for only a few minutes. However the rate of current is so slow before and after slack tide that it may "appear" to be slack for a long period of time.


Growing up on Malaspina Strait we liked to fish the slack, which could vary from 30 minutes to a couple of hours, depending on tide range and location.

It is fun and interesting to track the tides and times through Juan de Fuca and into/out of Georgia Strait.
