Upper Colorado River Watershed Snapshot: June 4, 2020

Drawing from data recorded on USGS gauges located around the Fraser Valley, this map compares measurements from June 4th with median flows from previous years.

The Upper Colorado River watershed experienced peak flows for the year on June 4, hinting that the impacts of climate change are already being felt in the Fraser Valley.

Predicted impacts from climate change in the Upper Colorado River watershed include:

  • Higher than average runoff earlier in the spring
  • Peak run off occurring in May rather than June
  • Lower than average runoff and reduced groundwater levels into the late summer and fall months.

In general, flows were well above average in early June, with the most pronounced flows in the upper reaches of the watershed marked by blue dots. Further downstream, green dots mark flows only slightly above average.
