a Current river discharge values are taken or calculated from data source indicated in supplementary material. See the annotated database reference list in supplementary materials for details of each value. Depending on data availability, the value may reflect either mean or median annual discharge.
b Change in annual river discharge assumes full implementation of the NRLP. Data sources are as given in Tables 2 and 3 (Dams and canals databases).
c For the Brahmaputra and Ganga rivers, change in annual discharge is also shown for affected tributaries (in italics). The sum of the discharge changes for tributaries is equal to the discharge change for the parent river.
d For the Torsa, only 75% dependable yield (the 1st quartile of discharge) was available.
e “Direct offtakes” reflects the sum of water taken or delivered directly to the Ganga, rather than to/from one of its tributaries.
