1/ D.P. is average deep percolation in acre inches per acre.
2/'D.P. reduction in comparison with six year valley-wide average of 16.1 acre inches/acre. Negative values represent
~,It loading greater than average.
Tons of salt per acre inch. Based on the Grand Val ley hydrosalinity model.
4/ Tons of salt per acre. Negative values indicate salt loading greater than ayerage.
