Stanislaus River Steelhead Life Cycle Monitoring Program
The Stanislaus River Steelhead Life Cycle Monitoring Program is an ongoing survey starting in 2021 that aims to estimate the amount of steelhead (Onocorhynchus mykiss) present in the Stanislaus River by recording steelhead and redds observed. In addition to estimating the amount of steelhead, the survey aims to collect data relevant to steelhead spawning, documenting environmental conditions such as temperature and flow, and recording other fish activity present. ## About This Federated Record This CNRA Open Data Platform record is based on metadata federated from the Environmental Data Initiative (EDI) Data Portal. Its purpose is to improve the discoverability of the data package through the CNRA Open Data Platform. The EDI Data Portal is the repository of record for this data package. Metadata, resource links, and supporting information displayed here may not reflect the latest updates available in EDI. Resources shown here—including Full Metadata, Provenance, and Data Quality Report—are provided to help users understand and evaluate the data package and the supporting information available from EDI. For the current data package, citation, DOI, data files, metadata, provenance, data quality documentation, revision history, and other supporting information, refer to the EDI data package landing page: https://portal.edirepository.org/nis/metadataviewer?packageid=edi.1662.2&key=vqSpNwnbe91Bi8trB5RY25CoPD4 Access requirements, permissions, and authorization policies for resources hosted by EDI are established and managed independently of the CNRA Open Data Platform.

| Data title and description | Access data | File details | Last updated |
|---|---|---|---|
stanislaus_carcass Steelhead carcass data. This dataset contains information on steelhead carcasses encountered during this survey (January-April) and the Chinook escapement survey (October-December). Fork length, sex, and location are recorded. Also recorded is whether or not the adipose fin is present, and whether or not scales, otoliths, or other biological samples were collected. | CSV (EXTERNAL DOWNLOAD) | 09/25/26 | |
stanislaus_red Steelhead and pacific lamprey redd data. This dataset contains information recorded on steelhead and pacific lamprey redds that were observed. Information such as latitude and longitude of each redd observed, dimensions of the redd, and whether fish were present on the redd can contribute to understanding steelhead and lamprey spawning habits, and subsequently, their population dynamics. | CSV (EXTERNAL DOWNLOAD) | 09/25/26 | |
stanislaus_steelhead Adult and juvenile steelhead survey data. This dataset contains the primary data collected for the survey: adult and juvenile steelhead, chinook, and lamprey observed. Also recorded is the number steelhead redds, steelhead carcasses, pacific lamprey redds, Sacramento sucker redds, and any unknown or unidentifiable redds. | CSV (EXTERNAL DOWNLOAD) | 09/25/26 | |
stanislaus_dailyinfo Daily environmental information. This dataset contains environmental variables recorded at the beginning and end of each survey section, such as weather, water temperature, secchi disk depth, and river flow. Flow data was plotted alongside adult and juvenile steelhead observed to examine any potential relationship. | CSV (EXTERNAL DOWNLOAD) | 09/25/26 | |
