Observed and urbanization-adjusted annual maximum peak discharge and associated urban fraction and precipitation values at USGS streamgage:
05528440 BUFFALO CREEK NEAR LAKE ZURICH, IL
![graph 05528440 Observed annual peak-flood magnitudes were adjusted to 2010 land-use conditions on the basis of panel data regression model with fixed effect analysis. The symbols presented in the figure are: "observed annual peaks", "adjusted annual peaks", and "fraction of urbanization in the watershed"](new_appendix_figures/sir20165050_05528440.fe_qr_only.jpg)
