The Cossatot River School District, including the Umpire school campus, is closed the remainder of this week due to an outbreak of mumps across the district. They are using three A.M.I. days for contagious disease. The parent/teacher conferences scheduled for this week have been cancelled and will be rescheduled at a later date. Students at Umpire and Cossatot River will return to school on March 25th, following spring break.
