Watermaster is composed of a nine-member board, with each member serving a one-year term. Six members are elected by water producers directly, two members are appointed by the Board of Directors of the Upper San Gabriel Valley Municipal Water District, and one member is appointed by the Board of Directors of the San Gabriel Valley Municipal Water District.

Several committees are formed out of the board membership and may also include advisory members who are not board members.
