Annual Report for Active IDOT Wetland Mitigation and Hydrologic Monitoring Sites: September 1, 2020 through August 31, 2021

Summaries of 15 wetland mitigation and habitat hydrology monitoring sites are included in this report. Each summary contains a location map, a site map showing field instruments, and graphs and tables of data that was collected during the 2020-2021 monitoring year. For wetland mitigation sites each summary includes the extent of area satisfying wetland hydrology criteria, a table indicating whether well locations met wetland hydrology criteria, a table providing gauged surfacewater levels that met wetland hydrology criteria, hydrographs from active wells and surface-water gauges, and graphs of local precipitation data for the period. Sites with incomplete data may not include these figures and will only have a text summary. Habitat hydrology monitoring sites will not have wetland hydrology area estimates but will include a summary of water quality data. Locations of wetland mitigation and habitat hydrology monitoring sites are shown on Figure 1, and a list of site names is presented in Table 1. Also, a summary of areas meeting wetland hydrology criteria for each site is provided in Table 2. Except where noted, all data included in this report are from September 1, 2020, through August 31, 2021, at IDOT’s request.
