ABSTRACT: Most lotic systems of south-central Minnesota are set in a landscape dominated by intensively drained row-crop agriculture.  The Minnesota River system has experienced a range of changing hydrologic conditions, including increased magnitude, timing, and frequency of high flows.  Flow disruptions, even on limited temporal scales, can alter energy flow and impair preferred habitats for many fishes including but not limited to, Emerald Shiners Notropis atherinoides, Spotfin Shiners Cyprinella spiloptera, and Carpiodes spp.  Correlation analyses and mixed models were used to evaluate fish growth increments as a function of various flow conditions.  Preliminary results suggest that hydrologic conditions that facilitate floodplain connections, even for brief temporal periods, may influence growth of juvenile fishes in the Minnesota River.  These influences, however as anticipated, appear to be beneficial for some species and detrimental to others.  Therefore, conservation actions will vary based on the targeted species and desired outcomes.
