BLM OR Fish Resident Arc Hub: Resident Fish Presence for Stream Management

A geospatial feature class used to determine the presence of resident fish species in streams, affecting protection buffer widths in land management plans. The data originates from the Hydro Update Project and is based on actual observations or modeled fish presence, with verification typically involving a fish biologist or trained specialist. It is published by the Department of the Interior and was last updated on April 14, 2026.

Use Cases

• Determining protection buffer widths for land management activities based on resident fish presence.
• Modeling fish habitat distribution based on observed and modeled presence data.
• Informing conservation and development planning based on stream-specific species verification.

Strengths

• Data is based on actual observations or modeled presence from the Hydro Update Project.
• Verification typically involved a fish biologist or trained specialist.
• Available in multiple formats including GeoJSON, CSV, and ArcGIS REST API.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Determination methods varied by district, which may affect consistency.
