<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;'>This dataset is a compilation of survey monuments as points used by the State of California, Department of Water Resources. The associated data is considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.6, dated September 27, 2023. A survey monument can represent a boundary location or be used a precise location used for mapping and precise engineering measurements. Boundary monuments are the corners of parcels or lines of easements that can only be visualized on the ground by setting markers, or survey monuments. A survey monument is a physical marker that locates a corner or line on the ground. They can be on a line or offset from a line, on, above or below the surface, noticeable or almost invisible. They take many forms but the majority of the monuments set for the state water project are a varying diameter of metal pipe set flush or below the ground with an aluminum cap stamped with a number representing the point.</span>

i15 Cadastral Map Index DWR

This dataset represents the cadastral maps created by the Geomatics branch in support of real property acquisitions within the Department of Water Resources. The geographic extent of each map frame was created after using all the spatial attributes available in each map to appropriately georeference it and create the extents from the outer frame of the map. The maps were digitally scanned from the original paper format that were archived after moving to the new resources building. As new maps are created by the branch for real property acquisition services, they will be georeference, attributed and updated into this dataset.     The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.6, dated September 27, 2023.   DWR makes no warranties or guarantees  either expressed or implied as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.   Original internal source projection for this dataset was Teale Albers/NAD83.

<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 State of California Department operates office buildings across the extent of the entire State. These offices include a range of building types, ranging from major offices, field support offices, visitor’s centers, labs, and warehouses. Some offices are dedicated to specific Divisions, and others include numerous DWR organizational units (e.g. “West Sacramento”). The list and locations were compiled from websites and DWR tables of buildings, and the DWR GIS workgroup was asked to provide QA/QC of completeness and accuracy of the locations. Quite a bit of feedback was offered, lending some confidence in this as a complete and accurate product. Offices do of course occasionally move, so these data could go out of date without maintenance, and use of the current version is warranted.</span>

i06 Precise Surveys StateWaterProject

Point feature class and related table containing the Precise Surveys measurement time series. Measurements include elevations, Northings and Eastings, distances, and point-to-point measurements. Northing and Easting measurements are in CA State Plane Coordinate systems, Elevations measurements are provided in NAVD88 or NGVD29. This dataset is for data exploration only. These measurements and point locations are not considered survey-grade since there may be nuances such as epochs, adjustments, and measurement methods that are not fully reflected in the GIS data. These values are not considered authoritative values and should not be used in-lieu of actual surveyed values provided by a licensed land surveyor. Related data and time series are stored in a table connected to the point feature class via a relationship class. There may be multiple table entries and time series associated to a single mark. Data was assembled through an import of Excel tables and import of mark locations in ArcGIS Pro. Records were edited by DOE, Geomatics, GDSS to resolve any non-unique mark names. This dataset was last updated 4/2024.

Specific conductance data was collected for the Department’s involvement in the South Delta Salinity Monitoring Special Study required by the State Water Boards 2018 amendment to the Bay-Delta Water Quality Control Plan (Bay-Delta Plan). The candidate dataset includes all data collected for the High-Speed Salinity Mapping component of the study between September 2021 and December 2023. The dataset contains specific conductance measurements collected at fixed time intervals while traversing channel reaches by boat. The dataset is comprised of date/time, run name, channel name, Lat/Long, speed over ground, course over ground, specific conductance (µS/cm), and temperature (C°). Sample water was pumped through a flow-cell, housing a YSI EXO2 sonde and conductivity/temperature sensor. Water quality measurements were collected at frequencies between 1-5 seconds and spatially located using a WAAS-enabled GPS receiver (Garmin GPS 16x). Transect routes encompass all reaches in the southern Delta identified, in the Bay-Delta Plan, as locations for future segment-based salinity compliance. The salinity transects were performed as a method to validate model outcomes, validate stationary, continuous water quality monitoring sites, inform understanding of tidal dispersion in hydrologically complex regions of the study area, and inform the development of protocols for segment- based salinity compliance.</span><br /></p></div>

Various primary sources were utilized, including: 1) a Valley-wide set put together by FEMA, the Corps, &amp; state OES, using the contracting services of Montgomery Watson Associates, for the 1983, 1986, 1995, and 1997 floods. 2) An older map from the early 1990's that was developed by Carl Hauge when he was a part of DWR's Central District that showed Delta levee breaks up until 1986. 3) A file that belonged to DWR Delta Levees (originally compiled when Delta Levees was part of Central District) by Ron Landingham and stored on Bernoulli disks. 4) J. Dudas observations while at DWR up until 2017. J. Dudas also refined many of the point locations in the other datasets by using historic aerial photography, as well as by identifying the scour ponds that correspond to the breaches in order to improve the locational quality. Delta reclamation district engineers also provided some of the information (particularly with respect to historic causes) in addition to verifying the DWR data.</span></p><p style='margin-top:0px; margin-bottom:1.5rem; 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;'><span style='font-family:inherit;'>An important point of clarification is that DWR Division of Flood Management has other sources for historic levee failures (including the ULE/NULE and California Levee Databases) that are not included here. There are some overlaps, but there are also significant omissions and or discrepancies between the various dataset sources. Synchronization of the datasets – and the work it would take to do that – has been considered but is not currently feasible. So the candidate dataset is to be promoted as a useful stopgap until such time as better historic definition can be performed.</span></p>

Thirteen habitat types are defined in this Atlas. The system was based on a USFWS for its national wetland mapping program....The system was modified to include those terrestrial habitats, such as upland, agriculture, and urban, which were not included in the USFWS system. In addition, an open water classification was used in place of the USFWS river classification where the bottom type could not be identified.&quot; -excerpts from the 1979 USACE Delta Environmental Atlas, 7/1979. Digital images were clipped prior to warping to reduce risk of error during processing due to excess background. Digital clipped images were registered to USGS DOQQ's in ArcView 3.x(ESRI) utilizing Imagewarp 2.x extension. 23 October, 2002. Projection: UTM meters zone 10, nad 83. Accuracy within acceptable 7.5 Minute USGS map accuracy standards (1:24000 scale). For this set, the minimum number of control points used was 6 with an average of 8 to 9 points used. The pixel size for this set is 5.0 feet per pixel. User notes about the accuracy of this dataset (J Dudas, 1/24/2003): The goal of this project was to produce positionally accurate polygons which preserved the polygon areas/shapes as indicated in the Atlas plates. Chico State registered the scans to UTM Zone 10/NAD83, but it was clear that the scans had all sorts of distortions in them for a couple of fundamental reasons. The original Corps Atlas maps appear to have been produced by a fairly rough mosaicking, and as a result do not always correspond particularly well with DOQQs. Furthermore, the warping in the photos appears to get worse near the edges of the source photos, which suggests to me that the original photos were used in their entirety, rather than clipped, in effect a sidelap/overlap of 0%. As a result, the polygons were modified to reflect where some of these areas appeared in the 1993 DOQQs, for example, a channel island or a stretch of forest. In other words, the Corps Atlas polys were used to produce the shape geometry, and then the 1993 DOQQs provided the base for the actual poly locations. This will explain the positional offset seen between these polys and the scanned Atlas photos.</span>
