Description:
Abstract:
Irrigation canals and ditches in the South Platte River Basin. Canals and ditches are assigned to a HydroBase Diversion structure with a WDID.
Purpose:
Display location of irrigation water and estimate the amount of loss for the SPDSS consumptive use model

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy is considered excellent. Each ditch was reviewed individually and matched to a HydroBase diversion structure.
Logical_Consistency_Report:
ArcMap 9.2 was used to perform a rigourous QAQC procedure for this layer. One-to-many relationships were built between the HydroBase diversion structure and ditches on WDID and between the irrigation service area and ditches on the WDID. Ditches were then reviewed individually to ensure they relate to the correct diversion structure and service area. The result is a product of very high quality. All ditches, canals, and laterals contain the WDID of the diversion structure from which they obtain water from. When a ditch or canal contain water from multiple diversion structures then multiple identical ditches exist.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Most ditches are originally from USGS DRG maps and contain the same horizontal accuracy as USGS DRGs. Some ditches were digitized from USGS DOQQs. Their positional accuracy is considered good.
Lineage:
Process_Step:
Process_Description:
Ditches were obtained from the SPMap Ditch layer. Throughout SPDSS Phases 1-3 the ditches were edited, modified, appended, and renamed with information gained from interviews with water users.

Process_Step:
Process_Description:
Ditches were joined to diversion structures on the name. Ditches were reviewed and those ditches which were accurately joined were given the WDID of the joined diversion structure.
Process_Step:
Process_Description:
Ditches were overlayed and intersected with irrigation service areas. The ditches that intersected with the correct irrigation service area were given the WDID of that service area.
Process_Step:
Process_Description:
Ditches that did not have a WDID were reviewed and given a diversion structure WDID where appropriate.
Process_Step:
Process_Description:
All ditches were reviewed in a rigourous QAQC procedure that related the ditches to diversion structures. The relationships for all ditches were checked and edited as needed.
Process_Step:
Process_Description:
Ditches that did not have a WDID were considered inactive, abandoned, or erroneous and were removed from the dataset.
Process_Step:
Process_Description:
Ditches were joined to HydroBase diversion structures and the HBName attribute was calculated.
