Abstract: A frame structure for use as a portable dam. Each frame structure is comprised of a support beam, a base beam and at least one brace beam connected together in pivoting relationship so that the beams may be folded down together for quick assembly and disassembly. The collapsed beams are configured to lie parallel to each other in a folded arrangement to permit efficiency in stacking multiple units together for storage and transportation. The erected frame structures are connected to each other and held in a spaced relationship through the use of couplers that are adapted to slide over the ends of the beams forming the frame structures. The individual frame structures may be erected in place in the water, or a section comprising several connected frame structures may be pre-fabricated and lifted and placed as a unit in the water. A stiffener member is affixed to adjacent frame structures to hold them together in rigid relationship.
