Beginning April 2001, the operation
of this gage was assumed by Idaho Power Company, which had previously
contracted with the USGS. Due to continuing interest for the most
recent 15-minute tabular data, that information is made available
through this web page. This data is PROVISIONAL and has not been
reviewed by USGS. For more information about this gaging station, or to
