Public Information Statement
National Weather Service Detroit/Pontiac MI

...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.
