For engineer Christopher Neudeck, the levee reinforcement near Discovery Bay is just one small piece of a giant challenge left by an extraordinary winter. “If that levee were to fail, the lake, the golf course, the commercial area in here, that would all go under water” says Neudeck, pointing to a map of Discovery Bay in his Stockton office. The last time KPIX covered his team at work was mid-winter, repairing a delta levee that almost failed on Tyler Island. Now it’s late June, and a new risk is flowing along California’s levees. The state is experiencing what Neudeck calls a “very unusual year. The snowpack has been really prolonged.”
