The Cosumnes River near Casa CW is un dammed, and thus a wild river that comes up and down depending on rain. Levees attempt to keep it in its bank during times of high water, but when it rains a lot, as it has this winter, those levees take a beating. Here are some locally taken photos of some worrisome erosion in the only things keeping the river from spreading out over the countryside.
Note: I'm far enough away from it that the casa will not flood, but some of my neighbors are at risk.
Thanks to R. Finney for the photos.
