I don't think Estes lake has bass fishing but do u guys know of any other lakes or rivers that have bass in this area? Smallmouth?

Many lakes have smallies, like Horsetooth, Chatfield, Bear Creek and Aurora. Many scattered metro area ponds have largemouths and some nice ones.

I can't speak for bass, I was just in estes park last week though.

A number of streams/rivers have good trout populations. 

 

Take your spinning rod, and half a zinker Z super glued to a 1/16th ounce jighead aka the ned rig(natural colors like green pumpkin work best).

Have caught my fair share of trout with it up there.
