Hydrologic Conditions Monitor (HCM) displays real-time hydrologic conditions and the status of Commission-regulated water-use projects, including passby flow requirements, consumptive use mitigation, and related basin-wide drought indicators.

Water Application and Approval Viewer (WAAV) provides access to water use projects regulated by the Commission.

The Continuous Instream Monitoring (CIM) provides public, real-time water quality data from over 60 stations throughout the Susquehanna River Basin. The program uses instruments to measure water temperature, dissolved oxygen, pH, and other parameters. The program is unique because the stations remain in the same location for years, allowing for long-term studies. Scientists, policymakers, and the public use data to make decisions about water management, assess trends, and study cause-and-effect relationships.

The Mine Drainage Portal offers public access to data on the water quality impacts from mine drainage in the basin, including chemical data from various sources. Users can search for sampling locations and data, view a map of mine drainage sample locations and impaired streams, and submit mine drainage data. The Commission's Mine Drainage Program involves assessment, planning, design, and construction of abandoned mine drainage and abandoned mine land restoration projects to restore impaired stream miles and lands. More information on the Commission's mine drainage activities and specific projects can be found in the Reports Library.

The Commissions's Sediment and Nutrient Assessment Program (SNAP) monitors 26 sites for nitrogen, phosphorus, and suspended sediment to calculate the amount transported at each site and to track trends. The SNAP network is part of the Chesapeake Bay Program's Non-tidal Water Quality Monitoring Network, and data analyses can be explored on an interactive map , or with charts and tables within the website. The network consists of six mainstem sites and 20 tributary sites across New York, Pennsylvania, and Maryland. Read more about Nutrients and Suspended Sediment int the Susquehanna River Basin.

The Water Quality and Biological Index Map allows users to assess and compare water quality and biological conditions throughout the Susquehanna River Basin. The map is based on over 19,000 water samples collected from 2000-2023, using three category scores and an overall water quality score. The Biological Index Map uses the Chesapeake Bay basin-wide index of biotic integrity (Chessie BIBI) to score macroinvertebrate samples collected in the basin, displaying biological conditions for individual sites and watersheds. Users can toggle layers, zoom to watersheds, and click on sample locations for additional information.
