Steelhead Critical Habitat Streams

This layer depicts areas designated for Steelhead Critical Habitat as well as habitat type and quality in the Southern California Coast Evolutionary Significant Unit (ESU).These data represent the stream segments identified as Critical Habitat by the National Marine Fisheries Service (NOAA Fisheries) Southwest Regional Office (SWR).The linework for this layer is based on the California Department of Fish and Game (CDFG) and Pacific States Marine Fisheries Commission (PSMFC) 1:100,000 scale stream-based routed hydrography. SWR biologists divided the routed hydrography into stream segments using the best available information to represent local Steelhead distribution and habitat. As a result, each segment has its own unique identifier (GIS_Link) and related presence and habitat information.
