Irrigated Lands
Irrigated Lands geodatabases provide irrigated land coverages, associated ditch headgates and wells, and relational tables for the years listed below. Zipped shapefiles include irrigated lands, ditch headgates, ditch service areas, and wells, where available.
Disclaimer: Irrigated lands delineation, crop typing, and other information is provided by DNR for informational purposes only. Data is created by a combination of automated and manual processes and accuracy is not guaranteed. Use of this data as a primary source in Colorado Water Court is not recommended. See GIS metadata and Basin DSS Task Memos for more information about creation of these GIS layers.

National Hydrography Dataset (NHD)
Please download the latest version of the NHD from the USGS. (From the left-hand 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.

DWR Irrigation Ditches
This data set shows the delineation of irrigation ditches in Colorado. Ditches have been matched to their point of diversion and mapped to their researched extent. In some cases, the data has been photo-revised and in other cases it has not. In any case, this data set is a 2nd generation of irrigation ditch data produced by DWR/CWCB staff and in some cases produced by consultants with input from DWR staff. This data set is also incomplete and will have frequent additions as DWR/CWCB staff complete review of ditches.
