Water Supply Update

Yosemite Falls January 2015

It’s one thing to visit web sites and digest multiple reports on the water supply, but long-time MOST readers know that we don’t consider that kind of analysis to be adequate.  Instead, we insist on personally assessing the situation, risking life and limb to get a real water supply update for our readers.  And that’s exactly what we did last week.  Which is why you were deprived of our posts for so long.

MOST and his intrepid support staff — including photographer Bob — ventured to Yosemite National Park in the middle of winter.  What we found was beautiful, but incredibly low on water.  Today’s photo is a good reflection of that dire situation.  Note the lack of snow on the ground!

Note also in the photo the ice dome that has formed at the base of the upper falls.  It’s cold enough that the droplets of liquid water can freeze during the plunge over the falls, so some of the water changes from liquid to solid, and the solid ice accumulates in this dome.  The dome tends to change in size depending on the temperature: an essential part of the Hydrologic Cycle is the transformation of water among the three states of matter — solid, liquid, and gas.

If you want to learn more about California Water Resources and our current drought, be sure to join me in a “hybrid” course this semester at Santiago Canyon College.  We’ll meet on campus just three times during the semester; the rest of the course is online.  So even if you’re not from the Orange County area, you might be able to join us.  See the following for more details:
