Categorical forecasts of streamflow are important for effective water resources management. Typically, these are obtained by generating ensemble forecasts of streamflow and counting the proportion of ensembles in the desired category. Here we develop a simple and direct method to produce categorical streamflow forecasts at multiple sites. The method involves predicting the probability of the leading mode (or principal component) of the basin streamflows above a given threshold and subsequently translating the predicted probabilities to all the sites in the basin. The categorical probabilistic forecasts are obtained via logistic regression using a set of large-scale climate predictors. Application to categorical...

These data were compiled based on field observations and available literature. Field observations of plant cover were made in September and October of 2013 and 2014, while trait measurements were made in September and October of 2014 and 2015. Field data was collected on sandbars along the Colorado River through Grand Canyon between river miles 0 and 226. Field measurements of specific leaf area, stem specific gravity, and total cover. Plant height was taken from the Flora of North America, the Jepson Desert Manual, or A Utah Flora. Seed mass values were available from the Kew Seed Information Database (http://data.kew.org/sid/). Photosynthetic pathway was compiled from published literature. The trait values were...
