The Passage Assessment Database (PAD) is an ongoing map-based inventory of known and potential barriers to anadromous fish in California. PAD compiles data from more than one hundred agencies, organizations and landowners throughout California, and allows past and future barrier assessments to be standardized and stored at one place. Please refer to the PAD program page on Calfish.org for more information about PAD and additional resources.
Map Viewer
The Passage Assessment Database (PAD) Map Viewer gives the user the ability to view maps that reflect statewide aggregated PAD data, and allows to analyze the passage barriers in relation to each other, in the context of a watershed.
Query Tool
The Passage Assessment Database (PAD) Query Tool gives the user the ability to define an “ad-hoc” query of a set of PAD Projects. The query results include the chosen columns and types of PAD data filtered by the user's selection criteria. Query results may be downloaded as a spreadsheet.
