Groundwater Current State
The Groundwater Current State webmap (link below) displays groundwater metrics based on monitoring wells within the state of Indiana with at least 30 years of observations. Several water level metrics are available for display to provide a visual representation of the current state of Indiana groundwater resources. These metrics include depth to the water table for the most recent water year as well as percentiles to convey how the most recent water year compares to the 29 previous water years at each of the sites. Descriptions of the various layers present in the webmap can be seen at the bottom of this page. Methodology details can be found here
Layers Present in Webmap
Mean Water Table [Depth below surface (ft)] - Average water table depth in the well over the most recent (current) water year.
End of Year Water Table [Depth below surface (ft)] - Water table depth on the last day of the most recent water year (September 30)
Percentile of Mean Water Table - Non-exceedance probability of the mean water table depth from the most recent (current) water year as compared to the previous 29 water years. [100% = highest water table]
Percentile of End of Year Water Table - Non-exceedance probability of the water table depth on the last day of the water year (September 30) as compared to the previous 29 water years. [100% = highest water table]
Percentile of Maximum Water Table - Non-exceedance probability of the maximum water table depth from the most recent (current) water year as compared to the previous 29 water years. [100% = highest water table]
Percentile of Minimum Water Table - Non-exceedance probability of the minimum water table depth from the most recent (current) water year as compared to the previous 29 water years. [100% = highest water table]
Percentile of Water Table Range - Non-exceedance probability of the water table range from the most recent (current) water year as compared to the previous 29 water years. [100% = greatest range]
