Workers struggle to pull an outlet hose for a pump over a dike at Oak Grove Lutheran school Sunday, March 29, 2009, in Fargo, N.D. The bloated Red River briefly breached a dike early Sunday, pouring water into the school campus and the mayor called it a "wakeup call" for a city that needs to be vigilant for weaknesses in levees that could give way at any time.
