- Review and coordinate Great Lakes-St. Lawrence River System forecasted and recorded lake-wide mean water level and beginning-of-month lake-wide mean water level information for publication in Canadian and U.S. Water Level Bulletins and News Releases. Coordination of recorded water levels occurs annually.
- Review and coordinate hydrometeorological data collection, coverage and timeliness and recommend modifications as necessary to meet the needs and accuracy requirements for water level forecasting, lake regulation, international studies and for other related uses. Ensure data and metadata are accessible to the full Committee, other agencies and the public through multiple avenues.
- Recommend relocations, additions or deletions to the networks in meeting the changing needs of users. For example, review the adequacy of the tributary water quantity gauging networks.
- Coordinate the following hydrometeorological data as it becomes
available and associated metadata for the Great Lakes-St. Lawrence River
System, including, but not limited to:
- Residual Net Basin Supplies (with input from the Hydraulics Subcommittee)
- Precipitation (land surface, lake surface and total basin)
- Evaporation (lake)
- Component Net Basin Supply
- Keep up to date on the hydrological models available for the Great Lakes-St. Lawrence River system and use them as much as possible for Subcommittee studies. Make available appropriate coordinated datasets for use in these models.
