Information Bulletin:

This information bulletin announces the availability of and describes the recent updates to the Fish Distribution Data Standard Version 2.0. 

The Fish Distribution dataset represents spatial location and basic information about the presence of fish by species. This dataset includes:

  • Resident Fish – fish that do not migrate out to the ocean but remain in freshwater.
  • Anadromous Fish – fish that migrate up rivers from the sea to breed in freshwater.
  • Non-Native Fish – fish that are not native to the system. 

Fish Distribution data informs resource management planning, project level National Environmental Policy Act (NEPA) analysis, Endangered Species Act (ESA) Section 7 consultation analysis, and restoration planning. Riparian Reserve land use allocations are designated on federal lands by Resource Management Plans (RMP) and vary in width, depending on fish distribution as well as stream periodicity. ESA Recovery Actions and habitat restoration activities rely on Fish Distribution data that extends across land ownerships. 

The following is a list of the changes for this version of the data standard:

  • Reformatted document to meet Section 508 standards and match the latest data standard template.
  • Updated section 1 to make it comply with the new data structure.
  • Updated FOIA category, records retention schedule text, and keywords.
  • Corrected sponsor.
  • Updated architecture diagrams.
  • Added field aliases, edit tracking fields, and default values for required fields.
  • Updated publication dataset section to match current document conventions.
  • Added attribute rules to editing procedures.
  • Dropped attributes related to USGS data structure and tools as they are no longer used.
  • Updated privacy impact assessment.
