Hydrographs of water level in the freshwater marsh of the upper Shark River at station MO215 (see Fig. 1b) for each year of the study (2004–2021). Individual color-coded lines correspond to each sampling year and illustrate the high degree of interannual variability in both the timing and magnitude of freshwater flows. The solid black line represents the long-term mean daily water level for the full period that MO215 has been recording data (1996-present) with the shaded area indicating standard error in water level across the dataset. The horizontal hashed line denotes the 30 cm threshold that corresponds to the beginning of marsh prey concentration in the river channels during falling water levels.
