Short summary
Short summary
Forecasting river flow months in advance is crucial for water sectors and society. In North America, snowmelt is a key driver of flow. This study presents a statistical workflow using snow data to forecast flow months ahead in North American snow-fed rivers. Variations in the river flow predictability across the continent are evident, raising concerns about future predictability in a changing (snow) climate. The reproducible workflow hosted on GitHub supports collaborative and open science.

Short summary
Rivers are valuable indicators of climate change when extensively monitored. We used an integrated monitoring program within a changing river basin to understand how sediment and dissolved organic carbon change across differing landscapes and runoff conditions. We show that delivery of sediment and dissolved organic carbon changes widely between years and rivers draining pristine or impacted catchments. This work demonstrates challenges facing river water users under a changing climate.
