CONDITIONS AFFECTING FLOW

MILES ABOVE MOUTH: 256.7 DRAINAGE AREA: 30810.0 POOL STAGE: 0.0

STREAM BED: gravel and sill

REACH: levees protect an area in the vicinity of the gage (RB) to

above 431.15 ft MSL.

REGULATION: Flow regulated by power plants and storage at numerous dams

upstream. Power operation at Wilson Dam 2-3/4 miles

upstream.

DIVERSION: none

WINTER: very little ice effect occurs.

TOPOGRAPHY: The RB is fairly high and will overflow only at extremely

high stages; however from below the highway bridge for

about half a mile, overflow begins above 18 feet stage.

Left bank is a high vertical rock bluff and is not subject

to overflow.

20.00 Alabama State Highway 20 is covered by water at the underpass
below US highway 43 and 72. The

underpass will likely be closed.

21.50 Water covers the parking lots of the marina at McFarland

the soccer fields and golf course within the park. Water is also
beginning to cover the road that

goes underneath U.S. Highways 43 and 72 at the new playground.

27.00 Moderate flooding. Flooding of industries near the river begins.
There are a few buildings below a

stage of 27 feet upstream of the railroad, but they are protected by a
dike that was not topped in

1973 (stage of 30.3 ft).

30.00 Widespread flooding of industries near the river is occurring.
