    Abstract

    Algal colonization and assemblage development were examined on unglazed ceramic tiles in flow-through troughs over a 42-d period (summer 1987) in the regulated upper Colorado River (?2400 m a.s.l.). The unusually constant discharge of the stream, coupled with the trough design, allowed the establishment and maintenance of four controlled current regimes that differed with respect to range of free-stream velocity and associated near-substratum hydraulic conditions: 1) depositional (free-stream current velocity
