Claim:
A deck drainage system, comprising: a water-receiving structure locatable under a deck; and a gutter connectable to the deck adjacent to an end of the water-receiving structure for receiving water from the water-receiving structure; wherein the water-receiving structure comprises a plurality of interconnected troughs, wherein each trough of the plurality of interconnected troughs comprises first and second opposing sidewalls; wherein the first sidewall of at least a first trough of the plurality of interconnected troughs and at least a successively adjacent second trough of the plurality of interconnected troughs comprises a vertical portion and a horizontal tab perpendicular to the vertical portion; wherein the second sidewall of at least the first trough and at least the successively adjacent second trough comprises a vertical portion and a channel having a horizontal upper boundary formed by a horizontal portion of the second sidewall; wherein the horizontal tab of the first sidewall of the first trough extends into the channel of the second sidewall of the successively adjacent second trough and wherein the vertical portion of the first sidewall of the first trough abuts the vertical portion of the second sidewall of the successively adjacent second trough; and wherein the horizontal upper boundary of the channel of the second sidewall of the successively adjacent second trough extends from a location that is directly vertically above a location on a bottom of the successively adjacent second trough between the vertical portion of the first sidewall of the successively adjacent second trough and the vertical portion of the second sidewall of the successively adjacent second trough past the vertical portion of the first sidewall of the first trough to a location that is directly vertically above a location on a bottom of the first trough between the vertical portion of the first sidewall of the first trough and the vertical portion of the second sidewall of the first trough.
