Abstract: Various embodiments of the present invention provide deck protection systems for use with a deck structure, including planks and support structures. One embodiment provides a body having a deep end, shallow end, a trough section, and opposing side edges. The opposing side edges support the deck protection system between two parallel support structures, and water falling between the planks is captured by the trough and flows from the shallow region to the deep region to an exit located in the deep region. The water passes through the exit and a spout, preventing water from touching the supporting structures and preventing water from falling directly below the deck.
