Many regulated streams are characterized by highly variable and unpredictable flow regimes. Since changes in streamflow directly modify physical habitat, streams with such highly variable flows provide highly unstable aquatic habitats. The authors evaluated the effect of artificial streamflow fluctuation on stream fish communities by comparing fish densities, in species and habitat groups, between two rivers differing in daily flow regime: one with a natural flow, and one with highly regulated flows.
