Really like this picturegraph of what a watershed is. In Feather River Country, where I live, the Feather River begins about halfway up the mountain, turns into three main branches, has formed deep canyons where it rushes down into the valleys, and ultimately flows into Lake Oroville. From there the water flows into the Sacramento Delta and then into the Pacific Ocean.
I wish the maps I have looked at would make it all more clear. In our neck o’ the woods, of course, the rain doesn’t often fall on the back side of the mountains and that is mostly a huge expanse of desert, including the Great Basin and the Mojave and Sonora Deserts.
And this also gives one an idea of why snow melt in the Sierra Nevada is so important. With as little rain as we get in the summer, snow on top of the mountains melts gradually and keeps the rivers filled, although by September the water level is often very low. That’s one reason the native Indian tribes used to have Snow Dances to pray for snow to keep the rivers filled in their valleys.
This is lovely. I’d actually hang this up somewhere in my home so I could look at it and be reminded every day of why I appreciate where I live so much.
Thank you Rose. River catchments is what my work is all about so I need to pay tribute once in a while. If you really want to hang it I could send it a full-size scan (my e mail is ziza00@gmail.com)
