  Description:
    Abstract:
      This digital dataset represents the Nutrient Limited Watersheds (NLW) as described by the Oklahoma Water Quality Standards. The OWRB defines NLW as "watershed of a waterbody with a designated beneficial use which is adversely affected by excess nutrients as determined by Carlson's Trophic State Index (using chlorophyll-a) of 62 or greater , or is otherwise listed as "NLW in Appendix A .." in chapter 45.

      This digital dataset is provided as a convenience to illustrate the Nutrient Limited Watersheds designated by the OWRB.  The authoritative designations are codified in the OWRB's rules maintained by the Oklahoma Secretary of State in Oklahoma Administrative Code Title 785, Chapter 45, Appendix A.  Proposed rules to amend and add to these Nutrient Limited Watershed designations are being considered by the OWRB and may become effective later in 2006.
    Purpose: The purpose of this digital dataset is to show the spatial extent of the watersheds contributing to the impaired water bodies.

    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: The 1:24,000 Watershed Boundary Dataset (WBD) was used to define the NLW watershed boundaries. In watersheds where the waterbody's drainage was smaller than the defined 12-digit units, the watersheds were on screen digitized from the USGS 1:24,000 Digital Raster Graphics (DRG). The screen resolution was set to 1:10,000.

      Process_Description: Individual 12-digit sub watersheds encompassing the waterbody's drainages were selected from the Watershed Boundary Dataset (WBD) and exported as a new shapefiles. The individual sub watershed were merged together to create a single polygon watershed. When necessary the watersheds were clipped to include only the upstream drainage above each waterbody's dam. There were 13 individual polygon shapefile produced
