RFI: Borrego Springs winter birding sites

Hi all,
I'm going to be in Bor Spr for 3 days over Xmas. I have very little experience birding there and would appreciate tips and directions for the best spots (I have heard about a water treatment plant, thrasher spots etc, but need directions).
Please reply off list.
Thank you and happy birding to all.
Steve
