Nerves are on edge in Vicksburg, Mississippi where the Mississippi River is headed for a historic crest in the next 24 hours.
This flood wall is being re-enforced to hopefully hold back the waters.
The river is expected to peak at least one foot above the 1927 record and could stay elevated for up to one month.
A snake advisory has been issued for the state because of the high waters.
Many residents of Vicksburg have evacuated their homes and headed for higher ground.
