Spirit Lake, IA (Northwestiowanow.com) — The Spirit Lake Fire Department was at the scene of a gas leak on the North shore of Big Spirit Lake for six hours Tuesday after a tree collapsed on a storage tank.

Fire Chief Pat Daly says the tree fell right on the valve that firefighters wanted to reach.

It’s likely the tree at 24580 McClelland Lane fell Monday night and wasn’t discovered until a cleanup crew smelled gas the next day.
