STEPINTOTHEFUTURE,STEPINTOTHEPAST GRAYSHARBORHERITAGEThe Chehalis River Surge Plaindo we mean by a surge plain?When tidewater comes up the river, the salt-heavy oceanwater sinks, pushing and lifting the freshwater to the top. The higherfreshwater floods the land and spreads out, running backward intosloughs where it remains until the tide changes course.Saltwater isn’t the slough empty at low tide?Normally, only the upper slough entirely emptiesat low tide. Many sloughs, including this one, receivewater run-off from the surrounding hills andthus are streams as well as sloughs.FreshwaterRiver EstuaryOceanmakes this surge plain special?This is one of the few places left where the mixing of saltwaterand freshwater occurs naturally. The coming together ofsaltwater and freshwater in a natural way creates a flood controlzone for man, a unique plant community and habitatfor fish and other wildlife.Slough atlow tide of –0.3,fall 1999Isthe tidecoming in orgoing outrightnow?
