Settling
Table R-2a. Settling velocities for each WASP segment using the centroid method. From/To columns show the
connections between water column and surface benthic segments. Settling velocities were calculated based on
empirical model peak concentration losses over distance. The centroid method applies the settling velocity of a site
to half the distance of the site above and below it.

Settling velocities for each WASP segment using the centroid method. From/To columns show the connections
between water column and surface benthic segments. Settling velocities were calculated based on empirical model
peak concentration losses over distance. The centroid method applies the settling velocity of a site to half the distance
of the site above and below it.

Settling velocities for each WASP segment using the bottom up and top down methods. Settling velocities were calculated based
on empirical model peak concentration losses over distance. The bottom up method applies the settling velocity of a site to the
site location and all the segments up to the site above it. The top down method applies the settling velocity of a site to the site
location and all the segments down to the site below it.

Velocity Calibration
The following tables are inputs to the WASP model simulated from 1/1/2011 - 12/31/2011 at USGS gage stations along
system. Inputs are based on observed daily data from each gage in cubic meters per second.
Table R-5. Flow inputs for the velocity calibration model based on USGS gage data. Residual flows between gages
were calculated and input into the model incrementally. Inputs were broken up evenly between gages resulting in
two to four increments depending on the distance between gages.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Flow inputs for the velocity calibration model based on USGS gage data. Residual flows between gages were calculated and input into the model incrementally.
Inputs were broken up evenly between gages resulting in two to four increments depending on the distance between gages. Flows are based on daily data. Units
are cms.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Flow inputs for the velocity calibration model based on USGS gage data. Residual flows between gages were calculated and input into the model incrementally.
Inputs were broken up evenly between gages resulting in two to four increments depending on the distance between gages. Flows are based on daily data. Units
are cms.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Flow inputs for the velocity calibration model based on USGS gage data. Residual flows between gages were calculated and input into the model incrementally.
Inputs were broken up evenly between gages resulting in two to four increments depending on the distance between gages. Flows are based on daily data. Units
are cms.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Flow inputs for the velocity calibration model based on USGS gage data. Residual flows between gages were calculated and input into the model incrementally.
Inputs were broken up evenly between gages resulting in two to four increments depending on the distance between gages. Flows are based on daily data. Units
are cms.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
GKM Release
The following are inputs to GKM Model simulated from 3/16/2015 - 11/16/2015 at USGS gage stations along system.
Inputs are based on observed daily data from each gage. From 9/11/2015 - 11/16/2015 observed data from the previous
year (2014) was used. At the time we modeled this scenario there was no data available and we wanted to continue the
time series beyond the current date. The Cement Creek boundary is the only streamflow input with at different time series.
At the Cement Creek USGS gage on the day of the spill, 8/5/2015, 15 minute data is used to give better resolution to the
plume time series as well as to capture the increase in volume at the station.
Table R-6. Flow inputs for the GKM model based on USGS gage data. Residual flows between gages were
calculated and input into the model incrementally. Inputs were broken up evenly between gages resulting in two to
four increments depending on the distance between gages.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Flow inputs for the GKM model based on USGS gage data. Residual flows between gages were calculated and input into the model incrementally. Inputs were
broken up evenly between gages resulting in two to four increments depending on the distance between gages. Units are cms.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Flow inputs for the Snowmelt Scenario based on USGS gage data. Residual flows between gages were calculated and input into the model
incrementally. Inputs were broken up evenly between gages resulting in two to four increments depending on the distance between gages. Flows are
based on hourly data. Units are cms.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Flow inputs for the Snowmelt Scenario based on USGS gage data. Residual flows between gages were calculated and input into the model
incrementally. Inputs were broken up evenly between gages resulting in two to four increments depending on the distance between gages. Flows are
based on hourly data. Units are cms.

Flow inputs for the Snowmelt Scenario based on USGS gage data. Residual flows between gages were calculated and input into the model
incrementally. Inputs were broken up evenly between gages resulting in two to four increments depending on the distance between gages. Flows are
based on hourly data. Units are cms.

Gold King Mine Release of Acid Mine Drainage to the Animas and San Juan Rivers
Initial concentrations of total individual metals and total metals - Xx (i.e., As) fortotal metals, arsenic, copper, lead, and zinc in the
snowmelt scenario. Inputs are from sediment concentrations on the last time step in the GKM release scenario. Dissolved
concentrations are calculated in the model using Kd values.
