Public Information Statement

National Weather Service Detroit/Pontiac MI

438 PM EDT Fri Mar 20 2026



...Changes for three river forecast points in Southeast Michigan to 

take effect April 1, 2026...



Consistent observational gage data is not available on the River 

Raisin at Tecumseh (TECM4) and Dundee (DNDM4) river forecast 

locations. River gage observations are critical for producing high 

quality forecasts, so after coordination with partners, including 

the USGS, the US Army Corps of Engineers, and Emergency Managers 

from Lenawee and Monroe Counties, the National Weather Service will 

discontinue forecast services for these locations, effective April 

1, 2026.



Forecast services will also be discontinued for the Shiawassee River 

at Fergus (FRGM4) effective April 1, 2026. In coordination with the 

USGS, the US Army Corps of Engineers, and Saginaw County Emergency 

Management, an assessment concluded that flooding in this reach of 

the river poses no significant impacts to life and property. 

Observed data from this point will continue to be available for 

informational use.
