Notes:
1.Percent of excavated material based on historical operations at site.-Accounting values based on measurements of actual tonnage.
2.Total excavated material of 200000 tons in 2016 and 128000 tons in 2017,distributed per(1).
3.and 4.Projected tons of material washed and not washed based on historical operations at site.Actual recorded values to be used in SW SP accounting.
5.Equal to 4%of washed material(3)+2%of material not washed(4).
6.Exposed surface area outside of lined areas.
7.Net evaporation based on gross evaporation(NOAA NWS-33)less 70%of average precisiteation(see Table 17).
8.Equal to(6)'(7). Accounting values based on measurements of actual ice cover.
9.1 ac-ft in 2016 and 1 ac-ft in 2017.Distributed based on(1),and included as part of dewatering(12).
10.Equal to(5)+(8).
11.Equal to unlagged mining depletions(10),lagged back to St.Wain Creek using AWAS program with following aquifer parameters:X=2000 ft;W=4173 ft;T=50000 gpd/ft,and S=0.2.
12.Based on average pumping over last year of 1030 gpm recorded at site.
13.Equal to unlagged dewatering pumping(12),lagged back to St.Wain Creek using AWAS program with following aquifer parameters:X=2000 ft;W=4173 ft;T=50000 gpd/ft,and S=0.2.
14.Equal to(11)+(12)+(13)+(9),since dust control comes from dewatering pumping that does not return to the river.
Negative values(-)represent net depletions to river system.Positive values(+)represent net accretions to river system.
