COMMENTS  & OUTSTANDING SATELLITE PHOTO OF MISS. RIVER & GULF

It was an outstanding photo – had to share with ya’ll.  I had heard that on the delta Georgianne, too bad it is going into the Gulf with the nutrient load and causing the huge “Dead Zone”  I was probably being a little too hard on farming methods causing the sediment in the river and Gulf – more likely it is geology-caused – all those great, deep clay and clay loam soils erode very easily and did pre-white man too.   But from what little of the river system I have seen in the Midwest there is little or no native riparian system left to trap sediment, pollutants or provide habitat.  I hope that is changing as we learn.  But I still see millions of tax dollars being spent making sections of river into hardened canals – a la San Antonio River Walk and Museum extension.  thanks for commenting, Mike  (We urge all of you readers to do so too and to add your own news items!

Mike, The Mississippi Delta is sediment starved in recent years. Instead of depositing in the delta, sediment is trapped behind dams up river. Then the levees in the lower region propel most remaining sediment into the deep gulf waters where it cannot build land. 
Thanks for sharing the satellite image.

st1\:* { BEHAVIOR: url(#default#ieooui) } Look at the results of many man- caused wounds to  “Ole Man River”: pollution, destroying riparian zone, poor farming conservation methods, city waste effluent & stormwater, destroyed wetlands, etc.   Is this happening to your river?   From: Susan
