ND = No Data* Code = Selenge River Project (SRP) followed by two digits for year, two digits for month and two digits for day and two digits for site number sequence for that day.
** = distance almost always based on GPS calculation as straight line distance
***Grazing Codes: 0=no grazing evident; 1=slight grazing; 2=moderate grazing; 3=heavy/mixed grazing; 4=heavy grazing.
****Erosion in Watershed Codes: 0=no erosion evident; 1=slight erosion; 2=moderate erosion; 3=heavy/mixed erosion; 4=heavy erosion.
*****Erosion in Watershed Codes: 0=no erosion evident; 1=slight erosion; 2=moderate erosion; 3=heavy/mixed erosion; 4=heavy erosion.
