Description:

Abstract:

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.

Purpose:

To accurately provide the delineation of irrigation ditches in Colorado.
