Digging a ditch can be complicated. I thought I heard the Overflow Spillway was never tested... probably because wasting water in California is a crime.
NPR said the overflow spillway had not been used in 50 years. Not sure if they had tested it since then. Meanwhile, we're looking at weekend temps in the 50's with zero flooding...not bad for the middle of February. In Michigan.
Just talked to my buddy who works for FEMA, he is working on the east coast at
the moment and just got word he *might* be going to California - "soon".
