Abstract:
This data layer represents stream segments above partial or total fish passage barriers in the Russian River watershed. Features from the original source data (see Originator information) were selected based on their spatial location within the Russian River watershed in Sonoma and Mendocino counties in California (the study area boundary of the Russian River Watershed Adaptive Management Plan project). This metadata file incorporates much of the information that was available in the metadata of the original source data. In addition information is provided from the Russian River Stream Crossing Inventory and Fish Passage Evaluation final report produced by Ross Taylor and Associates, 2003. This information is indicated in quotation marks.
Hydrography data: " Developed by Watershed Assessment Program, in cooperation with the USDA Forest Service Remote Sensing Lab. Includes separate linear and polygon layers. The procedures were based on BLM's Oregon/Washington Hydrography Handbook using the LLID routing approach. The base linework is from 1:24,000 Forest Service Cartographic Feature Files (CFFs) and 1:24,000 USGS DLG-3 files. The original files were edited and new linework added. This dataset has been modified for hydrologic modeling in a stream network. Source files by 7.5' quadrangle were edge matched and edited for connectivity. The stream network has been centerlined through waterbodies using artificial connectors. All arcs have been connected and oriented to flow downstream, and are routed. Lat/long identifiers (LLID) are used to uniquely identify the stream routes,and are available in the route attribute table. Available for download by river basin, or CD-ROM including roads and DEMs."
"The inventory and fish passage evaluation of stream crossings within the Russian River watershed was conducted between May, 2001 and March, 2003 under contract with CDFG. The primary objective was to assess passage of juvenile and adult salmonids and develop a project scheduling document to prioritize corrective treatments to provide unimpeded fish passage at road/stream intersections. The inventory was focused primarily on Sonoma County and
Mendocino County- maintained crossings within anadromous stream reaches within the Russian River basin known to historically and/or currently support runs of coho salmon (Oncorhynchus kisutch), chinook salmon (O. tshawytscha) and /or steelhead (O. mykiss irideus). However, a number of crossings within city limits and on private property were included."
Purpose:
This data layer was edited from its original source data set for inclusion in the Russian River Watershed Adaptive Management Plan (RRWAMP) and RRWAMP Baseline Watershed Assessment project. The intended use of this data layer in this project is to examine landscape or human factors to promote ecological health and sustainability within the Russian River watershed.
"Provides seamless enhanced hydrography data by river
basin, modified for hydrologic modeling."
