Crews are trying to repair a broken natural gas line that’s left some southern Iowans without heat. The break happened in the pipeline in Adams County just south of Prescott over the East Nodaway River. Lenox City Clerk Karen Zaabel says crews are on the scene, but it’s going to take awhile. She says they’re not sure what caused the break, but they have some ideas. They think it broke in the joint. She says with all the thawing debris going down the river, some must’ve hit the pipeline across the river and broke the joint. Zaabel talks about the residents without gas. She says they have a population in Lenox of 14-hundred with another 400 in Clearfield and another 16-hundred. So she says they get up near three-thousand without including the multiple residents in places like the county home. The break occurred late last night (Sunday).
