Here’s the latest on Portage, WI flooding based on the most recent official updates I can confirm:
- The Wisconsin River at Portage peaked around 20.47 feet in mid-April 2026, approaching the record level of 20.66 feet, and then began receding. Some areas near the Caledonia-Lewiston levee were affected, and a two-mile stretch of I-39 near Highway 33 required sandbagging to protect infrastructure. This situation prompted partial evacuations and ongoing road closures for safety.[1]
- Multiple local jurisdictions issued flood warnings and updates in April 2026, highlighting that several rivers were above bankfull and some areas could experience minor flood conditions, with warnings continuing as snowmelt and rainfall persisted. Residents and travelers were advised to avoid flooded roadways and monitor official road closure notices.[3][4]
- Public safety and emergency services remained active, including swift-water response capabilities, to support evacuations and access in flooded neighborhoods such as Lake Road and Blackhawk Road areas, while efforts continued to monitor levee performance and water levels in the Portage area.[1]
- In addition to local updates, several media outlets reported on stranded residents and ongoing flood watches in Portage during the peak period, with NOAA/NWS forecasts guiding local responses and preparedness measures; residents were advised to heed “Turn Around, Don’t Drown” for flooded roads.[2][6]
If you want, I can pull the latest official road-closure statuses for Columbia County and Portage specifically, or set up a quick alert to notify you of new flood advisories and status changes in Portage. Would you like me to do that?
