South Slough Reserve, Oregon

Tidal Range

South Slough tides are mixed semi-diurnal. The two low and high tides are uneven, typically with a very low tide followed by a very high tide, followed by moderate tides. The extreme spring tide daily range in water level is about 12 feet.

River Flow

The single largest system, Winchester Creek, flows north through the watershed for four miles before entering reserve. Most of the other significant freshwater contributions to the Slough flow from the more gently sloping eastern side of the watershed. Due to seasonal variations in freshwater flows, South Slough salinity profiles vary with the time of year.
