Environmental flows

The water needs of people and natural ecosystems are expected to become increasingly in conflict. Water managers are cognizant of these pressures, yet there remains a critical knowledge gap of the ecological tradeoffs associated with dam and flow management, including instream flows presently mandated in the Pacific Northwest and elsewhere. Our research aims to advance the science and develop the tools required for ecologically sustainable water storage and management, including understanding the type and timing of streamflows which promote the delivery of important goods and services and support native biodiversity.
