GFLOW model files used to generate probabilistic waste-water plume extents and contributing areas to supply wells for a proposed waste-water infiltration lagoon scenario, Lac du Flambeau, Wisconsin.

This data release contains files for three scenarios of an analytic element (GFLOW) groundwater
flow model with particle-tracking that were developed in cooperation with the Lac du Flambeau
Band of Lake Superior Chippewa and Indian Health Service to map the probablistic plume extent
for a proposed waste-water infiltration lagoon, along with maps to delineate the area contributing
recharge to supply wells under 2010 and 2035 pumping conditions. Monte Carlo methods were
used to run each scenario thousands of times using a range of parameters developed through
prior work (https://doi.org/10.3133/sir20145020). Results illustrate that most of the infiltrated
waste water would be expected to flow south, ultimately discharging to Moss and Fence Lakes.
Probabalistic areas contributing recharge to the supply wells did not overlap with the new lagoon
sites under 2010 pumping conditions, while the area contributing recharge under 2035 pumping
conditions shows a low probability of overlapping with the new infiltration lagoon. This USGS
data release contains input and output files as well as utility scripts to run a single realization
of the Monte Carlo simulations, though all of the parameters used for the Monte Carlo simulations
are also included in the associated *.ranvar files.
