Jim,
Somebody has probably already told you this but Kentucky Lake is up the
Tenn-Tom to its intersection with the Tennessee River and then down the
Tennessee.
Current on the Tenn-Tom is very dependent upon the amount of rain, and snow
melt if its springtime, in the mid west and northern portions of the US. If
the Mississippi and Ohio River levels get up the COE will direct a lot of
the flow from the upper Tennessee valley water shed that would normally up
down the Tennessee R to the Ohio R and then into the Miss R, down the
Tenn-Tom instead. They can do that by holding the water at Pickwick L&D and
opening the spillways in the dams down the Tenn-Tom.
Where the Tenn-Tom is a somewhat narrow canal the current picks up pretty
quickly with even a nominal amount of additional flow. The lower Tombigbee
is prone to flooding because of its low banks so modest high water can and
does pick-up a lot of debris. Rains in north central Alabama also adds to
the flow below where the Warrior River water shed comes into the Tombigbee
at Demopolis.
So with that said watch the amount of rainfall over the Ohio and upper
Mississippi valleys and plan your journey up the Tenn-Tom accordingly. If
there has been a lot of rain or heavy snow melt, wait a while.
There are web sites that will give you the current and projected flows at
each Tenn-Tom dam as well as the water levels. The problem I have is that
they give it in millions of cubit feet per second so unless I check it
enough to know what a normal lazily flow is I have no idea whether X million
cubit feet per second is fast or slow or in between.
Bill
