“…Reservoirs in Quebec, which produce an inversion of the natural annual cycle of rivers (maximum flows in winter and minimum flows in spring and summer), cause higher interseasonal and interannual variability of daily flows (e.g., [17][18][19][20]) downstream from associated dams than in natural settings. The ecological consequences of such high interannual variability have not yet been documented.…”

Abstract:The interannual variability of streamflow affects the composition and species richness of vegetation in low-flow channels and alluvial plains. Although climate conditions in 2003 and 2004 were nearly identical, large differences in streamflow were observed downstream from the Matawin dam. These differences resulted in numerous days without flow (no water release) during the growing period (May to August) in 2003, leading to man-made hydrological drought. While this drought had no effect on abiotic variables (grain-size distribution and nutrient concentrations in sediments), a significant decrease in the number of terrestrial species was observed in 2004 (year without drought) relative to 2003 (drought year) on three sand bars studied. This decrease is interpreted to result from prolonged submergence of the sites in 2004. Principal component analysis highlighted the effect of individual sites (first principal component) and of the interannual variability of streamflow (second component) on the number of species. The study suggests that, from a flow management standpoint, it is advisable to release enough water downstream from the dam during the growing season to prevent low-flow channel colonization by invasive terrestrial species.

In this study, Hydrologic regime alterations(magnitude, magnitude and duration of annual extreme, frequency and duration of high and low pulse, rate and frequency of water condition changes, Range of Variability Approach) were analyzed by using Indicators of Hydrologic Alterations at the 11 major multi-purpose dam. The analysis result of the magnitude of monthly water conditions during drought season, inflow was 6.38 ㎥/sec ～ 39.84 ㎥/sec and outflow was 20.36 ㎥/sec ～ 49.43 ㎥/sec, was increased 1.84 % ～ 200.98 %. The analysis result of the magnitude of monthly water conditions during flood season, inflow was from 79.06 ㎥/sec to 137.12 ㎥/sec and outflow was from 65.32 ㎥/sec to 80.16 ㎥/sec, was decreased from 18.19 % to 40.39 %. The analysis result of the magnitude and duration of annual extreme, 1-day minimum was increased 82.86 % ～ 2,950 %, but 1-day maximum was decreased 34.78 % ～ 83.96 %. The analysis result of the frequency and duration of high and low pulse, low pulse count was decreased 29.67 % ～ 99.07 % and high pulse count was also decreased 4.60 % ～ 92.35 % after dam operation. Hydrograph rise rate was decreased 15.84 % ～ 79.31 % and fall rate was 1.97 % ～ 107.10 %. RVA of 1-day minimum was increased 0.60 ～ 2.67, also RVA of 1-day maximum was decreased 0.50 ～ 1.00.
