Starting in December 2016 and over the following seven months, discharge data from IDA are being migrated to the National Water Information System Web Interface (NWISWeb) . This migration will occur one Water Science Center at a time (roughly by State). Once the transition is complete IDA will be discontinued. Please address any questions through the "Questions and Feedback" link above.
