Northman's point about the DWR ( more specifically, certain managers) trying to save face with their current actions is a very valid one.
I will give the UDWR credit for preceding forward with getting the permits to do the rotenone treatment, should the current experiment not reach its desired results. Otherwise, it would take several more years after a decision was made to rotenone, and start over, to work through the approval process.
