These photos were taken after 5 or 6 days of rain. The first 4 were taken in Newmarket NH. which is an old mill town. The river is funneled between the stone factory buildings and can not overflow. There was an incredible amount of power flowing in the river. It was making the ground shake. The covered walkway between the factories looked like it was going to be washed away, but it held strong.
The 5th photo is of Rochester, NH. Not nearly as much water here.
The 6th photo is the hydro dam in Dover, NH. It was making a considerable amount of power on this day.
