Discharge data past September 30, 2007 have been moved from IDA to the National Water Information System Web Interface (NWISWeb) . Historical instantaneous values for other parameters are now also available on NWISWeb and users are directed there, or to the related web services, for all data from October 1, 2007 through the present. IDA remains available for discharge data prior to October 1, 2007. Future plans are to move all remaining IDA data to NWISWeb sometime in 2013 at which time IDA will be discontinued. Please address any questions through the "Questions and Feedback" link above.
