No you do not need to add water, that will reduce the OG.
Most likely you just did not fully mix the wort and your top off water, so you got a flase reading. If it was an extract brew it is almost impossible to miss OG unless you added waaaaaay to much water. If the volumes were correct you are at your of of 1.071.
