Where Does Our Water Come From?

Snowpack melt off is the largest contributor to streamflow.

It also soaks into the ground to recharge the ​groundwater aquifer. The Deschutes River is the largest spring-fed river in the United States. Because of its close connection to groundwater, the Deschutes was historically a remarkably steady flowing river despite Central Oregon’s dry semi-arid climate. Snowmelt from the eastern side of the Cascades adds to the flows. About 80 inches of snow per year and 10 inches of rain account for the total precipitation in the Basin. When absorbed into the ground, snow and rain either enter into the water system through the ground (groundwater) or through rivers and streams (surface water).
