Rapid Watershed Assessments (by 8-digit Hydrologic Unit Sub basin)

The Natural Resources Conservation Service (NRCS) in Idaho is in the process of developing Rapid Watershed Assessments (RWAs) to provide a natural resource snapshot and overview of each Idaho 8-Digit Hydrologic Unit.  The RWAs organize resource information into one document that local conservationists, units of government, and others can use to identify conservation opportunities and direct technical and financial resources to the appropriate sub basins.  They provide a concise description of the sub basins' natural resources, resource concerns, conservation needs, and ability to resolve natural resource issues and concerns.  RWAs typically contain the following information:

  • Physical resources
  • Land use and land cover
  • Soil, stream, precipitation data
  • Resource concerns
  • Census and social data
  • Progress/Status of Conservation by Land Use
  • Estimated Future Conservation Practice Application and Associated Costs

Most of the data for the RWAs were collected through the National Land Cover Data Set, NRCS - National Resources Inventory, Census of Agriculture, and numerous Idaho State Agencies including the Idaho State Soil Conservation Commission and the Idaho Association of Soil Conservation Districts.  Local NRCS and partnership employee field staffs assisted in the compilation and verification of the data.

Over the course of several years, NRCS will be completing RWAs for the 8 digit Hydrologic Unit sub basins that are contained within Idaho's boundaries.  RWAs will not be completed for those sub basins that contain less than five percent private lands and those that are located more than ninety percent in adjacent states.
