The problem started on Thursday afternoon when a nearby levee overflowed and the water poured over that levee from the Novato Creek into a 600-acre field before flowing over the railroad tracks and then soaking Highway 37.

"We have no way to get it out of here," said CHP Officer Ross Ingels. "There are some pumps that the fire department and the county are getting but there's still more coming in than they're going to be able to get out." 

There is no estimated time of reopening.
