Local Diving Associations

The backbone of USA Diving is its 400 clubs. Each club belongs to a Local Diving Association (LDA). In most cases, the boundaries of each LDA usually follows the lines of the state, but some LDAs span several states or occupy a portion of one state. Each LDA is responsible for the USA Diving athlete and coaching memberships of its population.
