The Index of Watershed Indicators

This Index of Watershed Indicators (the Index) is the first national effort to organize national available aquatic resource information and present it at the watershed level. The Index is built on 15 different water resources indicators using information from a variety of public and private partners. Drawing on these indicators, the Index provides a description of the condition and vulnerability of each of the 2,111 watersheds in the continental United States. We will include Alaska and Hawaii later.
