Total pumped by LSPWCD records is 278.4 ac-ft
Application efficiency is 224.6 / 278.4 = 81 %; OK for center pivot
Well Owner owes LSPWCD: $2.00/ac-ft x(278.4 ac-ft) x 20.7 / 80.4 PLUS $25.00 Admin Fee =$168.36
LSPWCD owes Well Owner: $7.00/ac-ft x(6.2 ac-ft) _$43.40
Therefore NET that well owner owes LSPWCD is $168.36 -$43.40 =$124.96
