National Hydrography Dataset (NHD)
Please download the latest version of the NHD from the USGS. (From the lefthand menu choose "Get Data" then "pre-staged subregions" to get Colorado's data in the appropriate format.)

Source Water Route Framework
Source Water Route Framework is a dataset which includes a measured, named streams from the National Hydrography Dataset (NHD). This 10.1 File Geodatabase also includes confluence points and an associated table of stream mile locations of those confluence points. This dataset is intended to be used to calculate stream mile location of features using the ArcGIS Linear Referencing tools. See included document for additional details.
