UPDATE: Dakota Dunes officials advising residents to evacuate

Update (Monday, 1:30 p.m.)

DAKOTA DUNES, SD – Dakota Dunes Community Improvement District Board of Supervisors said Missouri River predictions have not changed and the resulting river levels will likely reach the top of the river bank protection.

Supervisors said as of 1:30 p.m. on Monday the National Weather Service predicts the Missouri River at Sioux City will reach 30.8 feet on Wednesday.

Residents are still being advised to relocate as soon as possible.

The Supervisors said the sanitary sewer system will only be shut down if the river breaches the protection in residential areas. They said preparations are being made to preserve the sanitary sewer system.

At this time the Supervisors do not believe water, gas and electric will be impacted.

According to Supervisors the main concern is the streets and other low lying areas becoming inundated with water if there is a breach or overtop.

Examples of low lying areas would include the intersection of Bison Trail, Levee Trail and Dakota Dunes Boulevard, along with East Pinehurst, West Pinehurst and Dakota Dunes Boulevard.

In the event of an overtop or breach, Supervisors will notify residents via text and email.
