Highway 75. The flooding is expected to be similar to the event
that occurred in 2006.

Precautionary/preparedness actions...

A Flood Watch means there is a potential for flooding based on
current forecasts.

Individuals living near the Big Wood River downstream of the magic
dam should be alert to possible flooding.
