Over Your Head Season 7 Episode 8 Rebuilding a Koi Pond Disaster

Geoff Mark attempted to build a koi pond with a waterfall to fulfill his wife Wendy's dream. But the result looks more like a Rube Goldberg creation than a serene water feature, and there have been structural and leakage problems from the moment the fish inhabited their new home. The weight of the structure is threatening the retaining wall behind it, and Geoff had to seal the area with an unsightly black tarp. Host Eric Stromer and carpenter Todd Davis help Geoff rebuild his misbegotten pond.
