Lake Washington Real-Time Portal Released

DSI recently developed a real-time model for Lake Washington, along with a public-access model portal. The portal allows users to view historical and current data on measured and simulated water levels, temperature, and velocity, presented in map view, time series, and vertical profiles. Users can also compare the data with the model and generate statistical measures…
