After a decade of nearly continuous drought, a levee break – even in an inherently flood-prone place like San Joaquin County – seems a strange and disconcerting sight. County officials have reported two such breaks in recent days, including this one on White Slough northwest of Stockton. No damage to buildings has been reported, though officials on Tuesday were assessing the harm to agriculture. Water has also sloshed over the top of levees or seeped through them in certain areas.
