A modular all-terrain algal production system that includes a plurality of segments. Each segment is made from one or more trays that are adapted to grow algae on their surface. The trays each have a flange end configured to be coupled to non-flanged end of an adjacent tray to form floways. Each floway has a rotatable surge bucket at one end that is able to hold water and spill the water in a wave down the floway into a catchment. The system is supported on uneven terrain by an adjustable structure arranged to provide each floway with a horizontal inclination.
