This week's bottom dissolved oxygen measurements indicate the expanding hypoxic zone from mid-river up to the Rt 50 bridge. Many of the tidal creek are also experiencing hypoxic conditions (2.0 mg/l or lower). This is due to the excessive nutrients causing the algae blooms, which then cause the low dissolved oxygen. Blue Crabs need above 3mg/l of dissolved oxygen to live, therefore at the moment the South River is not that hospitable for the blue crab. ---Diana
