For 20 years, Sarah has worked on water issues from the equator to the poles as a teacher and researcher. These days you’ll often find her getting wet (or searching for dry streams) in the Northern Rockies near the snow-rain transition because this is where climate change is already affecting what people eat and drink, and where they play and work. With students and colleagues and the local watershed partnership in her hometown in southeastern Idaho, she teases apart the three problems that drive public interest in hydrology: too much water, not enough water, and water of questionable quality.
