Integrated Watershed Monitoring Program

The Integrated Watershed Monitoring Program (IWMP) is our long-term ecological monitoring program. We study the state of our groundwater, streams, forests and wetlands to understand how healthy our watershed is and whether conditions in our ecosystems are improving, deteriorating or stable. This information informs our water and land management decisions.

IWMP Biennial Reports

These reports are summaries of IWMP data collected over two-year periods.

In 2014, IWMP refined the program to a rotating panel design where some sites are visited annually and others every other year. This rotating panel design maximizes the number of sites that are sampled in the monitoring program, while ensuring efficient use of resources.

The biennial reports present the current condition of the full panel of sites. The reports provide a complete picture of the overall watershed and the watershed zone status. The current condition of all sites monitored in the two-year panel is represented in maps, graphs, text and appendices. The reports also describe recent changes in the program and how data are managed and used.
