Source of the Danube, 51st of the Dog Days, 526 M.E. (Helios): As the water drops to unprecedented levels in the Danube River, old Nazi shipwrecks are emerging from the waters in Eastern Europe. A fisherman found a live WWII mine in the Danube in Slovakia, and in Serbia, a steam tugboat from the early 1900s emerged from shrinking waters of the Sava River. The ship, once a famed vessel known as the Slovenian, is called Sava's Titanic by locals.

Here in the United Snakes, a new framework for managing the shrinking Colorado River calls for California, Arizona and Nevada to reduce their consumption of water from the river by roughly 40%.  The cuts will require the three states to rely more on groundwater, to limit or even cut off some users, and to invest more in water-efficiency projects. They could also increase pressure on the agriculture industry, which uses nearly half of the water to grow crops used for animal feed, such as alfalfa. Building megacities and framing in the desert was never a sustainable proposition. 

I got my steps in today, 12,060 of them to be exact, in a 4.7-mile Madison. There were no active heat stress warnings here in Atlanta, but the 91° temperature and 68% humidity (dew point 74°) made me feel even hotter and more uncomfortable than when we were under one of the dreaded heat domes. In fact, the fatigue that quickly set in as I was walking is the reason I cut the walk short at a Madison rather than shooting for an eight-mile Van Buren or a nine-mile Harrison, although I did resist the temptation to take the early shortcut back to the house and walked that last mile. What doesn't kill you makes you stranger.
