Watch Carl Brooks transform his dream into a Pondless waterfall reality. My backyard is flat so I had to go vertical with my design. Plus I was restricted to the existing bed. My intent was to create a water feature to add an focal point in the backyard while masking the sound of the air conditioner and both goals were accomplished.
