Paleo-Dendrochronological "Tree-Ring" Hydroclimatic Reconstructions for Northern and Southern California River Basins

### Background
Tree-ring chronologies allow assessment of hydrologic variability over centuries to millennia, gives historic context for assessing recent droughts, and can be used in climate change research. Tree-ring based reconstructions of annual streamflow and precipitation provide a way to evaluate the observed record of streamflow and precipitation in the context of past centuries and reveal cyclic behavior that may not be detectable in the shorter observed records.

In all reconstructions, longer droughts (consecutive years below the observed record average) have occurred over the past centuries, in some cases double the length of the longest period drought in the observed record. In southern California, a number of the reconstructions indicate that the 2012-2016 drought was the worst 5-year drought in the past six centuries.

### Northern California Tree Ring Study 
For this study, 16 new tree-ring reconstructions of streamflow and precipitation for use in water-resources planning and operation are provided for the Klamath Basin and Sacramento and San Joaquin Basins. Analysis of droughts in the reconstructions for the three basins indicates the 1920s-30s and 1990s contained periods of drought notably severe in the long-term (centuries to millennia) context. However, the observed record does not contain the driest multi-decadal (50-yr) periods, and in the case of Klamath and San Joaquin, does not include the longest run of drought years.

### Southern California Tree Ring Study
For this project, six southern California records were reconstructed: four for total water year precipitation (Ojai, Lake Arrowhead, San Gabriel Dam, and Cuyamaca) and two for water year streamflow (Arroyo Seco and Santa Ana River), along with a reconstruction of Kern River streamflow in the southern Sierra Nevada. In addition, a reconstruction for Colorado River flow at Lees Ferry was updated. One of the most notable findings in this assessment is that, over the 20th and 21st centuries, southern California precipitation and streamflow, along with Kern River streamflow, have been more variable with correspondingly less year-to-year persistence, than over the past six centuries.

Vegetation - Suisun Marsh - 2024 [ds3221]

<div style='text-align:Left;'><div><div><p><span style='font-size:12pt'>To create the 2024 Suisun Marsh vegetation map, vegetation was interpreted from a mosaic of the true color imagery that was flown in June 2024. Polygons were delineated using heads-up digitizing (i.e., a photo interpreter manually drew polygons around each stand of vegetation) in Esri's ArcGIS Pro 3.4.3, and polygon attributes were recorded within a file geodatabase. All attributes were interpreted using the Suisun Marsh 2024 imagery as the base imagery. The photo interpreters obtained information primarily from the 2021 map and 2024 reconnaissance points as reference data, which were used during mapping to determine vegetative signatures and the appropriate mapping type for each polygon. Several other imagery sources were used as ancillary data, including 2024 NAIP, 2024 NAIP Color Infrared, all imagery available through Google Earth (including street view), and the 2021 NAIP imagery. Minimum mapping unit (MMU): Typically, the minimum mapping size is 0.25 acres. However, the photo interpreters use their best judgment to determine if a stand below 0.25 acre should be separately delineated. For example, a smaller polygon would be appropriate for any new visible occurrence of a non-native species of concern, such as Phragmites australis, Arundo donax, Carpobrotus edulis, Eucalyptus spp., and Lepidium latifolium. Minimum mapping width: There are many long and narrow polygons within the Suisun Marsh study area, most of which are roads, ditches, levees, and sloughs. The minimum mapping width is typically 10 feet; however, if small sections of a stand fell below the minimum width, the polygon was not split. </span><span>More information can be found in the project report, which is bundled with the vegetation map published for BIOS and available for viewing here: </span><a href='https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/3200_3299/ds3221.zip' style='text-decoration:underline;' rel='nofollow ugc'><span style='text-decoration:underline;'><span>https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/3200_3299/ds3221.zip</span></span></a><span> and here: </span><a href='https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=232836%20' style='text-decoration:underline;' rel='nofollow ugc'><span style='text-decoration:underline;'><span>https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=232836</span></span></a><span>. </span></p></div></div></div>

Urban Water Data - Drought Planning and Management

This data package aims to pilot an approach for providing usable data for analyses related to drought planning and management for urban water suppliers--ultimately contributing to improvements in communication around drought. This project was convened by the California Water Data Consortium in partnership with the Department of Water Resources (DWR) and the State Water Resources and Control Board (SWB) and is one of two use cases of this working group that aim to improve data submitted by urban water suppliers in terms of accessibility and useability. The datasets from DWR and the SWB are compiled in a standard format to allow interested parties to synthesize and analyze these data into a cohesive message. This package includes a data management plan describing its development and maintenance. All code related to preparing this data package can be found on [GitHub](https://github.com/FlowWest/urban-water-drought-data). Please note that the "org_id" (DWR's Organization ID) and the "pwsid" (SWB's Public Water System ID) can be used to connect to the various data tables in this package.

We acknowledge that data quality issues may exist. Making these data available in a usable format will help identify and address data quality issues. If you identify any data quality issues, please contact the data steward (see contact information). We plan to iteratively update this data package to incorporate new data and to update existing data with quality fixes. The purpose of this project is to demonstrate how data from two agencies, when made publicly available, can be used in relevant analyses; if you found this data package useful, please contact the data steward (see contact information) to share your experience.

California High Hazard Zones (Tier 2)

On October 30, 2015 Governor Brown issued an emergency declaration 
requiring public agencies to identify areas of tree mortality that hold 
the greatest potential to result in wildfire and/or falling trees and 
threaten people and property in these areas. Once identified, these 
areas will be prioritized for removal of dead and dying trees that 
present a threat to public safety. <br /><div><br /><div>Tier Two high hazard zones are defined by watersheds (HUC 12, average 
24,000 acres) that have significant tree mortality as well as 
significant community and natural resource assets. Work at the Tier Two
level addresses the immediate threat of falling trees and fire risk, and
 also supports broader forest health and landscape level fire planning 
issues.</div><div><br /></div>This service represents the latest official release of HHZ. It will be updated annually when a new version is released. As of June 2019, it represents HighHazardZones19_1.<br /></div>

Nonindigenous Aquatic Species (NAS) - USGS [ds731]

<div style='text-align:Left;'><div><div><p><span>This GIS dataset offers a link to the California portion of the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. The NAS program has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The program provides scientic reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The goal of the information system is to provide timely, reliable data about the presence and distribution of nonindigenous aquatic species. The NAS database contains locality information for more than 1100 species of vertebrates, invertebrates, and vascular plants. The NAS program provides a continual national repository of distribution information for nonindigenous aquatic species that is used to gain an understanding of aquatic introductions, identify geographic gaps, and access the status of introduced aquatic species nationwide. Data are obtained from many sources including literature, museums, databases, monitoring programs, state and federal agencies, professional communications, online reporting forms, and Aquatic Nuisance Species (ANS) hotline reports. The NAS program defines a nonindigenous aquatic species as a member(s) of a species that enters a body of water of aquatic ecosystem outside of its historic or native range. This includes not only species that arrived from outside of North America but also species native to North America that have been introduced to drainages outside their ranges within the country. Please visit http://nas.er.usgs.gov for more information and to see all of the products and data available through the NAS program.</span></p></div></div></div>

The dataset is a representation of the Class A year-round and Class B through H seasonal restrictions set forth in section 228.5 of Title 14 of the California Code of Regulations. This regulation governs the use of vacuum or suction dredge equipment in California under the Fish and Game Code, effective April 27, 2012. (2012 Cal. Reg. Notice Register, No. 19-Z, p. 641 (May 11, 2012).) Notwithstanding the regulation, the use of vacuum or suction dredge equipment as defined is currently prohibited by statute in all California rivers, streams, and lakes. (Fish and G. Code, 5653.1, subd. (b); see also Id., 5653, subd. (g) (definition).) It is also unlawful under current law to possess a vacuum or suction dredge in areas, or in or within 100 yards of waters, that are closed to the use of such equipment. (Id., 5653, subd. (e).) This dataset is an approximate depiction of the Class closures and restrictions in California Code of Regulations, Title 14, section 228.5.
