Today I was joined by participants from my graduate class in Snow Hydrology. We observed the snowmelt runoff condition, and measured the discharge, confirming no changes have occurred in the stage-rating curve.
Above you can see the typical snowmelt runoff pattern in the stage hydrograph. The larger peaks above 0.8m are all connected to rainfall events, while the regular sine-wave fluctuations are due to fine weather snowmelt (e.g. early May). These fluctuations are closely related to the energy balance of the snowpack and the diurnal change in air temperature.
