I don't think you are allowed on the dam itself. 
Especially in the aftermath of 9-11.

Here's the address of 2 web sites that have pictures
of the dam.

There is no bridge crossing the river at the dam.  The
closest one is Blue Point Bridge.  You could cross
there and hike upstream, but I think there is a sheer
wall cliff between the dam and the bridge on the south
side.


Here's the address of a web site that gives the flow
rates of all the streams in AZ.

http://az.waterdata.usgs.gov/nwis/current?type=flow
 
Look for a line after SALT RIVER that starts as
follows:
  09502000 SALT R BL STEWART MOUNTAIN D ARIZ  

It has the flow for that section of the Salt River. 
It's currently at over 300 cfs (cubic feet per second)
which is a moderate flow.  The water is probably
rather cold.

Good luck.
