Biological Endpoints
This dataset describes the biological condition of nearly 600 sites in Southern California streams based on the condition of benthic invertebrate communities, a key indicator of stream health. The California Stream Condition Index (CSCI), a measure of biological condition based on benthic macroinvertebrates, was calculated at each of these sites and provides a consistent way to characterize biological condition across multiple river-types. For more information on the CSCI, refer to the CSCI Fact Sheet. The underlying bioassessment data is from sampling programs supported by the California State Water Resources Control Board's Surface Water Monitoring Program (SWAMP).

OData query
Use the resource's OData URL and its field names for paging, selecting columns, or filtering rows.
ODATA_RESOURCE_URL?$top=5
ODATA_RESOURCE_URL?$skip=5&$top=5
ODATA_RESOURCE_URL?$select=FIELD_NAME&$filter=FIELD_NAME eq 'VALUE'Replace ODATA_RESOURCE_URL, FIELD_NAME, and VALUE with the details for the selected resource. See the OData query options guide (opens in a new tab) for more examples.
