Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Passage Assessment Database (PAD) geospatial file contains locations of known and potential barriers to salmonid migration in California streams with additional information about each record. The PAD is an ongoing map-based inventory of known and potential barriers to anadromous fish in California, compiled and maintained through a cooperative interagency agreement. The PAD compiles currently available fish passage information from many different sources, allows past and future barrier assessments to be standardized and stored in one place, and enables the analysis of cumulative effects of passage barriers in the context of overall watershed health. The database is set up to capture basic information about each potential barrier. It is designed to be flexible. As the database grows, other modules may be added to increase data detail and complexity. For the PAD to be useful as a restoration tool, the data within the PAD need to accurately depict the on-the ground reality of fish passage constraints. This requires the PAD to retrieve new barrier data and updates to existing sites and to have verified and vetted the information it receives. In 2013, new PAD data standards were designed to standardize this process, and refine the data in PAD making the data more robust. The standard is available online at: https://nrmsecure.dfg.ca.gov/FileHandler.ashx?DocumentID=78802. The new standards have been implemented for all new records since 2013. In the future, the new standards will be implemented for all existing records.

Copyright Text: Since the inception of the Passage Assessment Database, funding for the compilation of these data have been provided by the California Coastal Conservancy, U.S. Fish and Wildlife Service (USFWS), NOAA Fisheries and the California Department of Fish and Wildlife (CDFW). The CDFW Fisheries Restoration Grant Program is one of the most recent and longest funders of the PAD. The USFWS has recently provided funding for the compilation of miles upstream, etc. Pacific States Marine Fisheries Commission staff manage and compile data into this dataset. Datasets were collected and supplied by multiple agencies and organizations, and the PAD would not be possible without these datasets (see the "Source Citation" element (srccite) for more information). We would like to thank Daniel Wieferich from the United States Geological Service for metadata support. He reviewed and edited the metadata for compliance with the Federal Geographic Data Committee Content Standard for Digital Geospatial Metadata.
