From time to time, Delta Township experiences various severe weather occurrences. Two tornadoes have hit the Township in the past 33 years. The Township has placed 13 Public Warning Sirens throughout the Township to notify citizens in case of severe weather or other disasters. These sirens are tested the first Saturday of each month at 1:00 pm.  During severe weather, when a tornado is spotted on the ground in Eaton County, or approaching from a neighboring county, the sirens are activated when the possibility of eminent danger exists. Citizens are urged to take cover when the sirens have been activated.

Occasionally, heavy rains have caused flooding in low-lying areas, especially along the Grand River. During the past 20 years, many corrective measures have occurred. County drains have been enlarged and the Township has required developers to create many flood retention ponds and basins. Currently, a major flood plain project costing more than $46 million is underway. This project, consisting of four earthen dams, the widening of Carrier Creek and other tributaries will culminate in a 100-500 year flood plain district.
