ORIGINAL REFERENCE: Woodhouse, C.A., and J.J. Lukas. Multi-century tree-ring reconstructions of Colorado streamflow for water resource planning. In review, Climatic Change. GEOGRAPHIC REGION: Colorado, USA, South Platte River, Arkansas River, Colorado River, and Rio Grande Basins PERIOD OF RECORD: 1383-2002 AD DESCRIPTION: Tree-ring-based reconstructions of streamflow at 22 gaging stations in the South Platte River, Arkansas River, Colorado River , and Rio Grande basins of Colorado, USA. For details see the TreeFlow website at: http://www.ncdc.noaa.gov/paleo/streamflow/index.html DATA: Arkansas River at Caņon City Annual (Water Year, Oct-Sep) streamflow reconstruction Values in acre-feet Rec'n = reconstruction Gage = natural flow gage record from Hydrosphere Resouce Consultants To calculate the confidence intervals around the reconstructed streamflows, obtain the root mean squared error (RMSE) provided in the Validation Statistics table on the reconstruction page from which this data file was linked. To calculate the 95% confidence intervals, multiply the RMSE by 1.960, and add the result to each reconstructed flow to generate the upper interval, and subtract it from each reconstructed flow to generate the lower interval. To calculate the 80% confidence intervals, multiply the RMSE by 1.282, and then add and subtract the result as described above.
