DAKOTA DUNES, S.D. (KELO.com) — Dakota Dunes officials expect the nearby Missouri River to crest about 1 p.m. tomorrow.
Though the National Weather Service lowered the crest from 30.8 to 30 feet, officials consider the reduction is “minor” and that the levels are still at “potentially dangerous levels.”
They also said today’s 20-30 mph winds from the south were lapping against their flooding protection.
Dakota Dunes still recommends relocation to all residents.
Below is the letter Dakota Dunes sent to residents today.

Missouri and Big Sioux Rivers Update #8
To those of you who have left, thank you, we are glad you are safe!! The National Weather Service lowered the crest to 30 feet from 30.8 feet. The peak is now scheduled to arrive between 1 am Wednesday through 1 pm Wednesday and should slowly recede in the next few days.
One additional concern today is 20-30 mph winds out of the south lapping against our protection and potential rain in the forecast. While this reduction is welcoming news, the magnitude of the change is minor and we still believe levels are at potentially dangerous levels. We continue to monitor and maintain our protective measures 24/7. Additionally, as the peak gets by us, the Corps will begin increasing releases which will slow the drop in river levels.
So, for now, our message below is still applicable. This notice applies to all residential neighborhoods – all neighborhoods means all residential neighborhoods, including the Meadows, the Prairie and the Country Club. We still advise relocation to ensure your safety. We will revise as the river peaks and lower river levels develop.
The sanitary sewer system will only be shut down if the river overtops and/or breaches the protection in residential areas to preserve the infrastructure. We are making preparations to preserve the sanitary sewer system, but there will be a lot uncertainties in the short term, should a river overtop or breach occur. We do not believe water, gas and electric will be impacted at this time.
The main concern is that the streets and other low lying areas will be inundated with water if there is a River overtop or breach. Examples of low lying areas would include the intersection of Bison/Levee Trail and Dakota Dunes Blvd, along with East/West Pinehurst and Dakota Dunes Boulevard
In the event of overtopping or breach, notification will be sent out via text and email. Again, for your safety, we are advising all residents to relocate as soon as possible.
This could last for five days or more, so prepare accordingly. o Dakota Dunes Community Improvement District Board of Supervisors are not confident that our protection can withstand the high water level a third time this year.
Residents should plug floor drains and turn off irrigation systems before you depart. Turn off dehumidifiers, water softeners and air conditioners to protect your homes.
This relocation & River level are not expected to affect the Commercial areas or Dakota Dunes hotels, only the residential areas.
Please check on your elderly neighbors as they may not get notices electrically.
