- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, records good except for estimated discharges, which are poor, unless otherwise noted. Record quality ratings may not be included in the water-year summary for approved records newer than 09/30/2018. Record quality is still being rated internally. For questions about record quality ratings, please send email to gs-w-sd_NWISWeb_Data_Inquiries@usgs.gov.
Regulation by fish hatchery and by hydroelectric plant 0.5 mi upstream causes diurnal fluctuation, but since storage capacity is small, daily flows are not appreciably affected. Occasional minor upstream diversions by Lead-Deadwood Sanitary District out of drainage basin into Whitewood Creek Basin. Upstream diversions by Homestake Mining Company discontinued March 2003. Satellite data-collection platform at station.
