AndreaBozzo/ceres-open-data-index huggingface dataset:
California Population Trends by Geography

The datasets provide population estimate trends from 1998 to the current year for each of California’s 58 counties, further disaggregated by Detailed Analysis Units (DAUs) - the smallest geographic units historically used by the California Department of Water Resources for water planning as part of the California Water Plan. DAUs are subdivisions of Planning Areas and often align with county boundaries, although a single DAU may span multiple counties. They have traditionally supported water demand estimates based on crop and land use types.

Within this dataset, two data tables are provided:

1)  A table showing  [population trends by county and DAU](https://data.cnra.ca.gov/dataset/population-trends-by-geography/resource/751d4f96-7881-488b-9401-28fd32649c39), and 

2)  A table showing [population trends by county, DAU, and places]( https://data.cnra.ca.gov/dataset/population-trends-by-geography/resource/ce6e2a05-bbed-4fbe-80e4-91400e175727)

The population estimates in these tables were developed using U.S. Census 2000, 2010, and 2020 data, along with California Department of Finance (DOF) intercensal estimates. The county‑DAU table uses DOF July county totals, while the county‑DAU‑places table uses DOF January place totals. DOF produces population estimates twice each year—January and July. January estimates are available at the level of census places within each county, whereas July estimates are produced at the county level. As a result, county totals differ between the two due to six months of natural change (births, deaths, migration) and because January estimates incorporate preliminary vital statistics that are finalized in the July series. Throughout development, intermediate results were reviewed and adjusted as needed, applying professional judgment to smooth trends where appropriate.

Since the California Water Plan is retiring DAUs as its planning and analysis framework, future updates to this dataset will transition away from DAU based geography. Instead, population estimates will be provided based on other geographic units, such as the 8-digit Hydrologic Units (HUC8) defined by the U.S. Geological Survey’s Watershed Boundary Dataset.

A [dashboard](https://tableau.cnra.ca.gov/#/site/DWR_Planning/views/County_DAU_Places_Pop_Trends/JanuaryPopbyPlacesforacountyandayear?:iid=1) is available for visualizing population trends by county and DAU and places. Please note that county-DAU-places  values reflect DOF January estimates, while County-DAU values reflect DOF July estimates.

i02 Natural Communities Commonly Associated with Groundwater (NCCAG)

<span style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>The Natural Communities Commonly Associated with Groundwater (NCCAG) dataset is a compilation of phreatophytic vegetation, regularly flooded natural wetlands and riverine areas, and springs and seeps extracted from 48 publicly available state and federal agency datasets. Two habitat classes are included in the dataset: wetland features commonly associated with the surface expression of groundwater under natural, unmodified conditions; and vegetation types commonly associated with the sub-surface presence of groundwater (phreatophytes). The NCCAG dataset began as an amalgamation of vegetation and wetland datasets with different scales, resolutions, attribute details, and classifications. A working group comprised of DWR, California Department of Fish and Wildlife (CDFW) and The Nature Conservancy (TNC) further reviewed the vegetation and wetland datasets and conducted a screening process to identify the vegetation and wetland types considered to be commonly associated with groundwater (Klausmeyer et al., 2018). The NCCAG dataset can be used as a starting point to investigate and identify groundwater dependent ecosystems (GDEs) within a groundwater basin. Identifying GDEs requires detailed understanding of the land use, groundwater levels, hydrology, and geology of a location. This comprehensive understanding of geology, hydrology, and biology is not available at the statewide scale. Further investigation and verification of the connection and dependence between groundwater and mapped vegetation and wetlands at a local scale may be needed for water managers in sustainable groundwater management planning.</span>

California Snow Data

The California Snow Data page contains resources from the California Data Exchange Center (CDEC) in open and machine readable format. These resources include snow sensor and snow course metadata and measurements and snow water content data. Snow courses are typically sampled manually around the beginning of the month during the February through May period. The procedure for snow course sampling is detailed in the [Snow Survey Procedure Manual](https://cdec.water.ca.gov/cgi-progs/products/SnowSurveyProcedureManualv20141027.pdf). Snow sensor data is automatically collected at 15-minute intervals and is available in daily and monthly intervals in the resources below.

The source data and additional data and plots can be accessed from CDEC’s website (https://cdec.water.ca.gov/snow.html). For additional data visualizations, please visit the California Cooperative Snow Survey Program’s website and browse their dashboards (https://snow.water.ca.gov/).

Clifton Court Forebay Predation Study - Fish Sampling

This dataset is part of the Clifton Court Forebay Predation Study, a multi-year effort led by the California Department of Water Resources to understand the behavior and movement of predatory fishes and fish-eating birds within Clifton Court Forebay. The broader study supports requirements outlined in the 2009 National Marine Fisheries Service Biological Opinion and aims to evaluate conditions that contribute to fish predation risk.

This dataset contains data on predatory fish which were collected during the 2013-2018 CCFPS studies. Fish were captured using hook and line or gillnet sampling. Fish were assessed for previous tags, weighed and fork length measured and implanted with PIT tags and floy tags, some fish were implanted with Acoustic Tags.

Surface Water - Chemistry Results - CEDEN Augmentation

This dataset includes field and lab chemistry data that has been submitted to the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN), but has not been loaded into the CEDEN database. It is a subset of the chemistry data that has been submitted to CEDEN since approximately December 2020, and supplements the data found in both the main [Surface Water - Chemistry Results](https://data.ca.gov/dataset/surface-water-chemistry-results) dataset and the [CEDEN Query Tool](https://ceden.waterboards.ca.gov/CQT/Home/AqtTool) (i.e., this augmentation data is not included in the data available from either of those sources). For consistency, many of the conditions applied to the other CEDEN data found on this portal and in the CEDEN query tool are also applied to this supplemental dataset (e.g., no rejected data or replicates are included). However, this supplemental data is provisional and may not reflect all of the QA/QC controls applied to the regular CEDEN data.

This dataset also contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result (like the main [Surface Water - Chemistry Results](https://data.ca.gov/dataset/surface-water-chemistry-results) dataset referenced above).
