From: Impacts of a Rapidly Declining Mountain Snowpack on Streamflow Timing in Canada’s Fraser River Basin

The reconstructed hydrographs for the Fraser River at Hope based on the linear trends in (a) observed (obs) and (b) simulated (sim) 5-day moving averages of daily streamflow and their differences for water years 1949 and 2006.
A 10-day lag of the 2006 reconstructed hydrograph is also shown to illustrate the recent advance of the onset of the spring freshet.
