    Default Mississippi River Comparison

    Comparison of Harold Fisk's (US Army Corps of Engineers) 1944 maps from the "Alluvial Valley of the Lower Mississippi River" with modern day lidar-derived images of the river.

    That appears to be near Tunica, Mississippi. Tunica Lake on the right hand side of images. Present day casinos near the upper left.

    Cool!
    In the US this perverted idea of “blood and soil” over “constitutional principles” is the most radical and anti-democratic and anti-Conservative idea I have heard in my lifetime.

    Impressively detailed cartography, eh? Remarkable how they could get such accuracy.

    The Mississippi is amazing. It draws from such an expanse of the U.S. My buddy from Montana claims that the actual headwaters are in Montana. As I look at more modern maps, I'm inclined to credit that notion. There's a similar, but better version of this... just don't find it right now --

    That meander quilt is fabulous. From top to quilting, just amazing.

    Is there stream flow information about the Mississippi catchment area? In Aus the equivalent, the Murray-Darling basin, is 40% down on stream flows over the last 10 years.

    BTW the map supplied, and the quilt are quite stunning.

    BTW, New Delhi faces running out of water next year, and much of south asia is in the same situation. Just think of that.

    I'm sure there is, but don't know just where to find it. The following link is to the river level this year at my hometown of Greenville, Mississippi. Flood level is 48 feet. The river exceeded that on February 18 and remained above flood stage until July 21.

    pretty astonishing agreement between the lidar and the 1944 maps. it's a little surprising that such work would have been produced during the war.

    astonishing topography as well.

    Central North America has seen record (high) precipitation over the last few years. Just as the Mississippi has been dealing with record flows, all five Great Lakes are at or near their all-time seasonal highs. Climate related? Probably, but it is just so much more soothing to blame the “regulators”.
