) model results show spatial gradients of local R2 values with consistently higher local R2 values in the northern Cascades. This finding illustrates that different hydrologic landscape factors, such as geology and seasonal distribution of precipitation
, also influence streamflow trends in the PNW. In addition, the spatial analysis model results show that considering various geographic factors help clarify the dynamics of streamflow trends over a large geographical area, supporting a spatial analysis
approach over a spatial ordinary least squares (OLS)-estimated regression models for predicting streamflow trends.
