"Crowd-Sourcing Snow: The Value of Community Science for Oregon’s Water Resources" presented by David Hill, Professor, Civil and Construction Engineering. Water and snow are incredible natural resources in the Pacific Northwest, contributing to recreation, water supply, and ecosystem services. We are fortunate to have a breathtaking array of sources of information on water and snowpack, both long-term and short-term. This talk will focus first on snow, the many ways that we learn about our snowpack, and just what exactly is changing, and by how much.
