  4. Title: California Salmonid Habitat Inventory: Russian River Basin, California, 1996-2002

    Contributors:

    Summary: This line shapefile represents the Russian River Watershed portion of the California Salmonid Habitat Inventory- a quantitative stream habitat survey focused on stream habitat restoration. Field biologists walk in-stream from confluence to headwaters of streams identifying pools, riffles, and flatwater areas as individual habitat units. Quantitative attributes include width, depth, substrate, bank vegetation, and slope to help identify restoration potential, stream health and monitoring potential. This data is inteded to aid in internal managment descisions regarding stream restoration projects and potential. Circuit Rider Productions and National Oceanic and Atmospheric Administration (2002). California Salmonid Habitat Inventory: Russian River Basin, California, 1996-2002. Circuit Rider Productions. Available at: http://purl.stanford.edu/cz715gw6055 All stream surveys are dynamically segmented against 100k base hydrography routes. The Dynamic Segmentation process is accomplished by 1) Preparing a hydrography arc coverage with a unique numeric value for each named stream 2) Ensuring flow direction for each stream 3) Building route/section topology for each stream 4) Preparing the habitat table as linear event data with a)measure distances based on field inputs and b)a unique key value for each named stream 5) Calibrating routes based on field input from habitat table 6) Displaying habitat tables in ArcView, converting to ArcView shapes and distributing to field personnel. 1. DFG has obtained US Geologic Survey (USGS) Digital Line Graph (DLG) 100,000 scale hydrography (See Appendix for Hydro Meta Data and structure). In 1993, the US Environmental Protection Agency (EPA) attached the River Reach File Version 3 (RF3) addressing system to California's hydrographic coverage Arc Attribute Table (.AAT). Arcs along the same named watercourse share a common primary name code, or PNMCD. The unique key value for each stream is the EPA national standard PNMCD. 2. Prior to building hydrography route/section topology, streams must have consistent linear direction. I developed an Arc Macro Language (AML) method for establishing direction of all streams based on topology with no operator (See Appendix for flow.aml and lake.aml). This process pathwalks each named stream from its headwaters to its mouth and ensures all arcs point downstream (including double lined streams). The DLG MINOR5 field is populated with the arc numeric sequence of each stream from the mouth. 3. I developed an ArcEdit AML which creates Route/Section topology (See Appendix for mkroute.aml). The blanket Arc level MAKEROUTE command will not ensure direction of all routes. The AML creates one route for each unique PNMCD, in which the beginning measure of the route is at the streams confluence (arc MINOR5 = 1 from flow.aml) and the ending measure is at the streams headwater. The resulting Route Attribute Table (.RAT) has one record per unique PNMCD. The resulting Section Attribute Table (.SEC) has one record for arcs along each PNMCD. 4. Preparation of habitat data as event tables contains the following processes: A) Insure the table has a properly populated route relate item and B) create and populate measure items. In some cases field personnel will not have the PNMCD value for the surveyed stream, and will enter instead a latitude and longitude of the stream confluence, the township range and section number (called legal) and/or the stream name from the USGS 7.5 Minute Quadrangle. By cross referencing the quadrangle, lat/lon coordinates, legal description or the stream name with the RF3 file, I find and enter the proper PNMCD value in the habitat table. Each habitat table data will relate to the .RAT on the PNMCD. The habitat table contains one record per habitat unit. The LENGTH field is the length of each habitat unit, measured in feet. Measure fields FROM, TO (for linear events), and LOCATION (for point events) are added to the habitat table. The FROM field is equal to the previous FROM value (0 for the first record). The TO field is equal to the FROM field plus the LENGTH field. The LOCATION field only populated when point event locations occur. While occurring anywhere in a habitat unit, point events are surveyed with the same length as a habitat unit. The LOCATION field equals half of the FROM FROM field plus the TO field. Measure items are converted to meters, the units of the hydrography coverage projection. Each record of a habitat table will relate to the .SEC on the measure items FROM, TO or LOCATION. 5. A point coverage for each survey, is made from each tributary's confluence or road crossings and the end of the survey. The end of survey point is digitized from a photocopied USGS quadrangle. The points are attributed with the length to the mouth taken from the habitat table, in meters. The Arc command CALIBRATEROUTES uses the point coverage to correct the arc measured distances with the field observed distances. 6. In Arcview, a view is added to a project and the hydrography route topology added to the view. The habitat event table is added to the project. With the view the active document, ADD EVENT THEME from the VIEW menu is chosen. The Add Event Theme dialogue box is populated, and the survey is displayed as an event theme. The THEME CONVERT TO SHAPE menu choice converts the event theme to a shape file. The shape file can be displayed and classified on any or multiple fields in the Habitat Inventory. The process is repeated for point events." This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  7. Title: Evolutionary Significant Unit Boundaries, Chinook Salmon: Russian River, California, 2002

    Contributors:

    Summary: This line shapefile of evolutionary significant unit boundaries was compiled from various sources based on written descriptions in National Marine Fisheries Service (NMFS) status reviews (available upon request) and mapping provided by NMFS. An Evolutionary significant unit, or ESU, of Pacific salmon is considered to be a "distinct population segment" and thus a "species" under the Endangered Species Act. Initial boundaries were derived from USGS 1:250,000 scale hydrologic unit boundaries. Drainage basin delineation from blockages was based on 1:100,000 stream hydrography and/or and available digital topography(1:250,000). Species do not necessarily inhabit all drainages or river reaches depicted. This dataset includes evolutionary significant unit (ESU) polygons depicting major basins within the current known range of each ESU, and were modified based on migration blockages and known fish distribution.

    Summary: This dataset contains regions representing the domains of the digital update units from National Hydrography Data and features were selected based on their spatial location within the extent of the Russian River basin and contains reach codes for networked features and isolated lakes, flow direction, names, stream level, and centerline representations for areal water bodies. Reaches are also defined to represent waterbodies. This dataset describes the lakes of the Russian River basin and is intended for hydrography analysis and planning. Circuit Rider Productions and National Oceanic and Atmospheric Administration (2002). Digital Update Unit Regions: Russian River Basin, California, 1999-2002. Circuit Rider Productions. Available at: http://purl.stanford.edu/mv287rt1135 The accuracy of the attributes of the Digital Line Graph data is estimated to be 98.5 percent. One or more of the following methods were used to test attribute accuracy: - manual comparison of the source with hardcopy plots. - symbolized display of the digital line graph on an interactive computer graphic system. - Selected attributes that could not be visually verified on plots or on screen were interactively queried and verified on screen. In addition, software validated feature types and characteristics against a master set of types and characteristics, checked that combinations of types and characteristics were valid, and that types and characteristics were valid for the delineation of the feature. Feature types, characteristics, and other attributes conform to the Standards for National Hydrography Dataset (USGS, 1999) as of the date they were loaded into the database. All names on reaches were validated against a March 1999 extract from the Geographic Names Information System. The entry and identifier for the names match those in the Geographic Names Information System. Features found on the ground may have been eliminated or generalized on the source graphic because of scale and legibility constraints. In general, streams longer than one mile (approximately 1.6 kilometers) were collected. Most streams that flow from a lake were collected regardless of their length. Only definite channels were collected so not all swamp/marsh features have stream/rivers delineated through them. Lake/ponds having an area greater than 6 acres (approximately 2.4 hectares) were collected. This layer is presented in the WGS84 coordinate system for web display purposes.

  12. Title: 1000 Meter Resolution Bathymetry Grid of Exclusive Economic Zone (EEZ): Russian River Basin, California, 1998

    Contributors:

    Summary: Eez1000 is a 1000 meter resolution statewide bathymetric dataset that generally covers the Exclusive Economic Zone (EEZ), an area extending 200 nautical miles from all United States possessions and trust territories. The data was adapted from isobath values ranging from 200 meters to 4800 meters below sea level; therefore nearshore depictions ARE NOT ACCURATE and "flatten out" between 200 meter depths and the coastline. The data is intended only for general portrayals of offshore features and depths. The Department of Fish and Game (DFG), Technical Services Branch (TSB) GIS Unit received the source data in the form of a line contour coverage (known as DFG's eezbath) from the United States Geological Survey (USGS). The contour data was converted to a TIN (triangulated irregular network) using ArcView 3D Analyst and then converted to a grid. The contour data was previously reprojected by TSB to Albers conic equal-area using standard Teale Data Center parameters. Some minor aesthetic editing was performed on peripheral areas using the ARC/INFO Grid EXPAND function. The image version was created using the ARC/INFO GRIDIMAGE function. Please see the attached metadata file "eezbatcall.doc" or the DFG coverage metadata "eezbath.txt" for further source data information.

Juvenile Salmonid Abundance Monitoring: Maacama Creek, Russian River, California, 1991-2001. Circuit Rider Productions. Available at: http://purl.stanford.edu/dm867xc0810 Juvenile abundance monitoring was conducted within "index zones". Each stream was divided into upper, middle and lower reaches, based on elevation, average gradient, and distance from the Russian River, and an index zone was select from surveys within each reach. Index zones were established during the first study year and surveyed for habitat condition. Each index zone was then broken down into habitat unit types (pool, riffle, glide), in which a unit is defined as a continuous portion of the stream of variable length, within which only one habitat type is present or is dominant. Juvenile abundance monitoring was conducted in selected units rather than the entire index zone. However, mapping is at the scale of index zone and the pooled results from units within each index zone are presented here. Fish were sampled in selected units within each index zone by repeated passes through the unit with a beach seine. Salmonids were identified to species (steelhead, coho) and measured (fork length). In some years steelhead densities were too high to safely measure all samples. A representative subsample (reported here) was measured to establish length frequency estimates for each year class. Monitoring was conducted at the beginning (July) and end (October-November) of the summer dry period to enable estimation of juvenile growth rate.
