Data Use Policy

Users of these data should understand issues related to sampling error, measurement error, and others. An excellent introduction to some of these issues is available on this site describing forest measurement and modelling error (courtesy of Cris Brack, Department of Forestry, Australian National University).

Developers of this site also request that any publications using data from these watersheds include the following paragraph:

Some data used in this publication were obtained by scientists of the Arizona Watershed Program and were made available through the Managing Arid and Semi-arid Watersheds website (http://ag.arizona.edu/OALS/watershed/). This publication has not been reviewed by those scientists. These watersheds are operated and maintained by the Rocky Mountain Research Station, U.S. Department of Agriculture, Fort Collins, Colorado.

If you agree, here are two access points to the Beaver Creek data:

• Search by data type - search by data type (streamflow, precipitation, etc.), dates, etc. for each of four watersheds, Beaver Creek, Castle Creek, Sierra Ancha, or Whitespar. (IE 5.0 recommended for the graphing tools)
• Search by map - use a map to locate the data you want
  • Beaver Creek
  • Castle Creek
  • Whitespar
• A GIS visualization tool is available for Soil lost assessment with USLE Model
