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 Caon 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.
