And they basically say that in this online article....................................but from what the plaques around the Jeff memorial and the fdr memorial........it seems that they are saying they basically made it from nothing..............a lie.............that pic was taken by Titan Ramsey Peale in 1863...........almost 20 years before the Army Corps of engineers supposedly built East Potomac park.......West Potomac park..........and the Tidal basin......................


Photo courtesy of the Library of Congress, LC-USZ62-127632.The Washington Canal, which incorporated part of Tiber Creek, ran along the north edge of the National Mall (now Constitution Avenue) connecting the Capitol with the Potomac River. The canal is clearly visible along the right side of the photo above, taken from the Capitol during the Civil War. Sewage was dumped into the canal and flowed to the river onto the flats just south of the White House grounds. Because sewage accumulated on the flats as opposed to draining out to the river, the area became extremely filthy, had a foul stench, and became a breeding ground of disease. While officials debated whether action should be taken to correct this health hazard, the final straw came in February 1881 when a huge snowfall melted causing the Potomac to flood across the Mall to the National Botanical Gardens at the base of the Capitol.
