Reply #32: During the Floods of the earl 1990s, the LOWER MISSISSIPPI ran LOW

[happyslug]

You had massive flooding in the UPPER Mississippi and Missouri Rivers but the Ohio was running low, so no flooding south of Cairo Illinois (Where the Ohio and Mississippi join). The reason for this was a massive High Pressure system stayed over the Ohio Valley, keeping it dry (Almost Drought Conditions). The High Pressure System also blocked the path for storms going east, so the Missouri and Upper Mississippi Rivers received what was normal to be received for both rivers AND THE OHIO.

Thus it it is possible for the Lower Mississippi to be unaffected by these storms (as it was NOT affected in the storms of the early 1990s). Ho bad the lower Mississippi river gets depends on how bad the Ohio is, and the Ohio seems to be at present at normal if not lower then normal amount of water.
