I've got reports in from my cousin in Slidell of no flooding there, but extensive flooding in towns like Indian Village, Turtle Creek and Middendorf. All smaller north of NOLA cities and towns. Another cousin, a merchant marine, has been onboard ship in the New Orleans harbor this whole time - needless to say he's reported in and has some impressive photos to share. He's waiting on clearing to be able to post/share them.
Thanks for all your updates, Sheila.

hazards affecting land
even though isaac is no longer a hurricane...life-threatening
hazards from storm surge...inland flooding...and tornadoes are still
storm surge...the combination of a storm surge and the tide will
cause normally dry areas near the coast to be flooded by rising
waters. The water could reach the following depths above ground if
the peak surge occurs at the time of high tide...
* mississippi and southeastern louisiana...4 to 8 ft
* alabama...2 to 4 ft
* south-central louisiana...1 to 3 ft
* florida panhandle...1 to 2 ft
the deepest water will occur along the immediate coast in areas of
onshore winds. Surge-related flooding depends on the relative
timing of the surge and the tidal cycle...and can vary greatly over
short distances. For information specific to your area...please
see products issued by your local weather service office. Near the
coast...the surge will be accompanied by large and dangerous waves.
based on observations from national ocean service tide gauges...at
new canal station louisiana...a storm surge of near 6 feet is still
occurring on the southern shore of lake pontchartrain...and a storm
surge value of near 5 feet is occurring at waveland mississippi.
wind...tropical storm conditions will continue across the warning
area through this morning.
rainfall...isaac is expected to produce total rainfall accumulations
of 7 to 14 inches...with isolated maximum amounts of 25 inches
possible...over northern and eastern louisiana....much of
mississippi...southwestern alabama...arkansas and into southern
missouri through friday. These rains could result in significant
lowland flooding. The heavy rain potential will be spreading
eastward this weekend into portions of the mid-west and ohio valley
tornadoes...tornadoes are possible along the central gulf coast
region and parts of the lower mississippi river valley through
surf...dangerous surf and rip current conditions will continue to
affect the west coast of florida and the northern gulf coast for the
next day or so.
next intermediate advisory...100 pm cdt.
next complete advisory...400 pm cdt.
The outer bands of Isaac are now moving into St. Louis. We just had a tornado warning a few minutes ago. There have been a few heavy downpours, but right now it's let up somewhat. But tonight and tomorrow, we are expecting 3-6 inches of rain. Thank goodness it's nothing like IKE, which caused major flooding, including boat rescues where you'd never expect. The storm sewers were just overwhelmed.
