Here's a report for ya...
there are often fish west of the line through these three points:
RB A
N32 51.204 x W117 16.235
RB B
N32 51.361 x W117 16.240
RB C
N32 51.915 x W117 16.228
You can even catch yt there year round

.
I wouldn't fish east of this line, there might be fish but they are expensive.
