Abstract:
This data set contains the boundary of the Rio Puerco watershed.

The watershed boundary was developed from USGS digital elevation data in the following steps: 1. The highest-resolution digital elevation quads available in 1993 were mosaiced into a single grid that extended beyond the boundaries of the Rio Puerco watershed. Most of these had 10m horizontal resolution; 60m and 3 arc-second data were interpolated and substituted where necessary (12 quadrangles). 2. The hydrologic function FLOWDIRECTION of ARC/INFO's GRID analysis package was applied to the mosaic. 3. The SINK function was used to identify and count cells where flow was discontinuous. 4. Quad boundaries were edited as required to fill gaps and provide flow continuity across the boundaries. Steps 2 to 4 were repeated until there were no identified sinks along quad boundaries. 5. The hydrologic function FLOWDIRECTION of ARC/INFO's GRID analysis package was applied to the mosaic. 6. The FILL command was used to fill pits and to repair elevation data errors internal to the mosaic's quadrangles. Steps 5 and 6 were repeated until a continuous flow surface was generated. 7. The cell closest to the Rio Grande (i.e., the "pour point" of the Rio Puerco basin) was identified from the flow-direction grid. 8. The BASIN function was used to identify all cells that flow to the identified pour point. 9. The boundary of the basin's cells was generated with the GRIDLINE command in ARC.

Processing software was ARC/INFO 6.3.

Purpose:
This data set was created to digitally represent the boundaries of the Rio Puerco basin.

Intended use of data: These data are typically used as base data for other coverages, and should be used at scales of 1:500,000 and smaller. The data are intended for use as a general reference to the extent and boundaries of the watershed.

Attribute_Accuracy:
Attribute_Accuracy_Report: Attribute accuracy for this data set is assumed to be 100%.
Logical_Consistency_Report:
Attributes and processing steps were consistent for the entire data set.
Completeness_Report:
Various cartographic representations exist for the boundary of the Rio Puerco basin. Significant variations of these representations occur in the area of the El Malpais lava flow in (or out, according to the analysis) the southwestern boundary of the basin. This is an area of complex topography and disconnected drainage. Improved representation of this portion of the basin boundary depends on acquisition of more reliable source data.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Source digital elevation data along the basin boundary has horizontal resolution of 30m. Except in the area of the El Malpais lava flow and in areas where the basin boundary is on flat terrain, the horizontal accuracy of the basin boundary is estimated at 60m. In flat areas and in the El Malpais, accuracy is undetermined.
