Streamflow data are critical for decision-makers from local to regional scales who are responsible for an array of topics ranging from real-time water management to long-term water resources planning. Through this project, we engaged a stakeholder advisory group to identify and compile critical streamflow monitoring metadata from 32 different organizations across the Pacific Northwest and created an interactive data visualization. We also distributed a survey to capture information about the organizations monitoring networks and quality assurance protocols and convened roundtable discussions in each state to gain additional insight into the challenges that organizations are facing and to identify priorities in regard to improved quality and accessibility of streamflow data.
