1 IOOS in the Great Lakes: Supporting Management of Drinking Water Quality Kelli Paige GLOS Program Coordinator

2 Lake St Clair St Clair River Detroit River Goal Reduce health risks and costs associated with pollutant spills in the Lake Huron to Lake Erie Corridor Desired Outcomes Timely response to spill events by water intake plant operators Timely response to spill events by water intake plant operators More efficient and effective spill response / search and rescue More efficient and effective spill response / search and rescue Protection of human health Protection of human health Major Elements Link 2d model for corridor to NOAA Great Lakes Forecasting System Link 2d model for corridor to NOAA Great Lakes Forecasting System Generate 3d public domain model Generate 3d public domain model Use 3d model to support water intake risk assessment work Use 3d model to support water intake risk assessment work

3  Predict currents, water-level for Lake St. Clair, St. Clair River, and Detroit River  Nowcasts every 3 hours, Forecasts every 12 hours  48 hour forecast HECWFS

5 Management Uses Feedback: How can this aid in spill response and planning? Next Steps: - Calibrated model to spill observations 3 dye releases in St. Clair River - Generated a spill reference library Based on different spill scenario simulations Simplified spill information for planning response - Metro Beach/Clinton River forecasting Aid in Metro Beach quality forecast Increased resolution near Metro Beach

9 Additional Applications Issues & Modeling needs Navigation needs (water levels, currents Search and Rescue Recreational boaters (>150,000) Petrochemical spills Drinking water safety Swimming beaches, water quality Habitat restoration projects ‘hotspot’ for invasive species Capabilities Real-time and forecasted currents and water levels throughout the HEC Output via web-interface or raw-data Validated results for currents and water-levels Spill information (scenario or forecast) –Travel time, duration, concentration River plume tracking & nearshore predictions
