The dams along the Colorado River create what two lakes?

Question

This is a U.S History Question

Answer 1

Lake Powell & Lake Mead?  

Answer 2

Then why is it posted in the travel section if it is a history question???? shouldn't it be in the history section?  

I would suggest you try looking at a map of the US southwest, and follow the river, and figure out where the lakes are.  I'm pretty sure this is your homework, and YOU should be doing it yourself.

BTW, there's more than two.
