Southern Sea Otter Range - CWHR M164a [ds3383]

<div style='text-align:Left;'><div><div><p style='margin:0 0 0 0;'><span><span>CWHR species range datasets represent the maximum current geographic extent of each species within California. Ranges were originally delineated at a scale of 1:5,000,000 by species-level experts more than 30 years ago and have gradually been revised at a scale of 1:1,000,000. Species occurrence data are used in defining species ranges, but range polygons may extend beyond the limits of extant occurrence data for a particular species. When drawing range boundaries, CDFW seeks to err on the side of commission rather than omission. This means that CDFW may include areas within a range based on expert knowledge or other available information, despite an absence of confirmed occurrences, which may be due to a lack of survey effort. The degree to which a range polygon is extended beyond occurrence data will vary among species, depending upon each species’ vagility, dispersal patterns, and other ecological and life history factors. The boundary line of a range polygon is drawn with consideration of these factors and is aligned with standardized boundaries including watersheds (NHD), ecoregions (USDA), or other ecologically meaningful delineations such as elevation contour lines. While CWHR ranges are meant to represent the current range, once an area has been designated as part of a species’ range in CWHR, it will remain part of the range even if there have been no documented occurrences within recent decades. An area is not removed from the range polygon unless experts indicate that it has not been occupied for a number of years after repeated surveys or is deemed no longer suitable and unlikely to be recolonized. It is important to note that range polygons typically contain areas in which a species is not expected to be found due to the patchy configuration of suitable habitat within a species’ range. In this regard, range polygons are coarse generalizations of where a species may be found.

Ground Water - Water Quality Results

<p>Groundwater quality data and related groundwater well information available on the page was queried from the GAMA Groundwater information system (**[GAMA GIS](https://gamagroundwater.waterboards.ca.gov/gama/datadownload)**). Data provided represent a collection of groundwater quality results from various federal, state, and local groundwater sources.  Results have been filtered to only represent untreated sampling results for the purpose of characterizing ambient conditions. 

Data have been standardized across multiple data sets including chemical names and units. Standardization has not been performed for chemical result modifier and others (although we are working currently to standardize most fields). Chemicals that have been standardized are included in the data sets. Therefore, other chemicals have been analyzed for but are not included in GAMA downloads. Groundwater samples have been collected from well types including domestic, irrigation, monitoring, municipal. Wells that cannot accurately be attributed to a category are labeled as "water supply, other". 

For additional information regarding the GAMA GIS data system please reference our **[factsheet](https://www.waterboards.ca.gov/publications_forms/publications/factsheets/docs/gama_gis_factsheet.pdf)**. </p>

Vegetation - Sonoran Mojave Desert [ds3199]

<div style='text-align:Left;'><div><div><p><span style='font-size:10pt'>California Department of Fish and Wildlife (CDFW) contracted Aerial Information Systems (AIS) to create a fine-scale vegetation map of portions of the Mojave Desert and Sonoran desert ecoregions that are not currently covered by existed fine-scale vegetation mapping, an area of 4,399,242 acres. The mapping area encompasses multiple counties including Inyo County, Riverside County and San Bernardino County. The minimum mapping unit (MMU) is 10 acres for desert types and 1 acre for non-desert types. For special stands including: wetlands, riparian, and rock outcrop; the mmu is 1 acres or ¼ for non-desert types. Landuse types had an mmu of 2.5 acres.  Wash types were mapped with a 5 acre mmu. The vegetation map adheres to the 2008 National Vegetation Classification Standard (NVCS) and the Manual of California Vegetation (MCV). </span></p><p><span style='font-size:10pt'>The project was conducted in 3 phases.

Suisun Marsh Salinity Control Gates Log

This log of operations includes: flashboard installation and removal dates, when tidal operations were started and stopped, and notes any technical issues.

This current document is an Excel file that contains the data as a Table. The Table can be sorted or filtered, and can be read by scripting languages such as Python or R. The date and time are stored together in the DATETIME field. The GATE 1, GATE 2, and GATE 3 fields state whether each gate is operating in Tidal Mode, set to Open, or set to Closed. The ACTION field states what operational change has occurred.

The timestamped records go back to May 5, 2018. If prior dates are needed, refer to the Historical (Archived) Suisun Marsh Salinity Control Gates Log PDF, which contains records going back to November 1, 1998. This document replaces the Archived version because the Archived version did not contain a timestamp for every record. For the records that did have a timestamp, the timestamps were placed in the REMARKS field. This issue, along with the document being a PDF file, created a problem for reading the data into time-series analysis software.

DSM2 Input 2026-06-29 historical update

Version "DSM2 Input 2026-06-29 historical update" is based on version "DSM2 Input 2026-04-16 historical update" (which incorporates the changes from the Monitoring Special Study version of DSM2), and includes the following changes:

Some cross-sections in Middle River are notched by adding a narrow "V" shape to the bottom. This is done to help prevent drying up. In the previous
version, notching was done to a bottom elevation of approximately -10 feet NAVD88. This release modifies the notching to a bottom elevation of
approximately 0 ft NAVD88.

The output location file output_stage_calib_mss.inp was modified to include output locations for stations CIS and MHR.
