IOOS in the Great Lakes: Supporting Management of

Drinking Water Quality

Kelli PaigeGLOS Program Coordinator

Huron - Erie Corridor

Lake St Clair

St Clair River

Detroit River

GoalReduce 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

More efficient and effective spill response / search and rescue

Protection of human health

Major Elements Link 2d model for corridor

to NOAA Great Lakes Forecasting System

Generate 3d public domain model

Use 3d model to support water intake risk assessment work

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

Management UsesFeedback: 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

Additional ApplicationsIssues & 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
