Let's say there is a certain density of hydrosols in the water column that reduce visibility to 10 ft. If the water column increases by 10% ( a 4 ft tide at a location where the depth is originally 40 ft) the hydrosols decrease by about 10% (9% more precisely) and the change in visibility is roughly 10%, or from 10 ft to 11 ft, or not much for a typical tide. This does not consider the long time it takes to increase the tide - 6 hours - during which the "clean" water has plenty of time to get dirty due to surf, and that the new water is not very clean to begin with.
