It’s believed the cold temperatures may have been the cause of a water main break in the city of Tenaha Monday morning, forcing the dismissal of classes at Tenaha ISD at 10 a.m. Tenaha ISD Superintendent Scott Tyner says the problem left all his campuses without water. Tyner advised City of Tenaha repair crews were telling him the water-line break should’ve been repaired Monday afternoon, and classes will go on as scheduled today.
