Spring Runoff Can Change Tidal Flows

Spring runoff from snow melt can impact tidal flows in some cases producing a "continuous ebb" current during a flood. Athough not certain from our limited research it appears that the runoff could be a surface water effect.  The surface layer adopting the directional flow from the runoff.  In any case, planning based on tide and current tables can go awry as we found ploughing into an apposing current up Greenville Channel.
