Bibliography Background About KRIS
Trinity River Basin Sediment Study by Graham Matthews and Associates
Graham Matthews and Associates' (2003a) Sediment Source Analysis for the Mainstem Trinity River, Trinity County, CA includes Upper Trinity Basin data: "The purpose of this report is to compile, summarize, and analyze sediment production data for the Trinity River watershed that could be used for TMDL development. The sediment production data is then integrated with other geomorphic information to develop a preliminary sediment budget for portions of the Trinity River watershed. This study combines office-based analyses of aerial photographs and GIS coverages with extensive field data collection and inventories, including considerable streamflow and sediment transport data collection." Data may include wild fire, timber harvest, roads, landslides and sediment transport rates.
U.S. Fish and Wildlife Service Water Temperature Data
The U.S. Fish and Wildlife Service Arcata Field Office has deployed automated temperature sensors throughout the Klamath and Trinity River watersheds, including the Upper Trinity in 2003. Data from the Upper Trinity are for three tributaries, Stuarts Fork, Swift Creek and Coffee Creek, that were once anadromous fish habitat. U.S. Fish and Wildlife Service has published numerous reports which utilize the water temperature data they collect (Guillien, 2003; Zedonis, 2003).
Water temperature references used in KRIS are based on Pacific Northwest wide literature on salmonids and temperature (Armor, 1990; McCullough, 1999; Sullivan et al., 2000; Welsh, 2001). See the KRIS Temperature Background page for more information.
Upper Trinity Basin Historic Photos from Trinity County RCD and Corrigan Family
The Trinity County Resource Conservation District was responsible for the updating of KRIS Version 3.0 and took initiative to also capture some excellent historical photos of the upper Trinity River in an area now submerged under Trinity Reservoir. These photos were contributed by Sue Corrigan and family and provide views of the old Van Matre homestead, Trinity Dam under construction and the filling of the reservoir. The Trinity lake and dam are part of the Central Valley Project, funds for construction of the initial features of the Central Valley Project were provided by the Emergency Relief Appropriation Act of 1935. The Secretary of the Interior authorized the project and the President approved it on December 2, 1935. The Shasta and Trinity River Division were authorized by Public Law 386, 84th Congress, 1st Session, approved August 12, 1955. Construction of the lake and dam begin in 1957 and concluded in 1962. The lake was full in 1964.
Upper Trinity Basin Climate Data
Rainfall and snowfall data for the Upper Trinity Basin was downloaded for use from the California Data Exchange Center (CDEC) web site as text files and converted into Dbase IV for use in KRIS. Relative location maps are also downloaded and can be viewed as Pictures associated with climate Topics. Snowfall data are displayed for April to allow inter-annual comparisons. Data collection in other months is too sporadic to allow for substantial comparison.
Trinity River Flow Data
Trinity River flow records are taken mostly from data collected by the U.S. Geologic Survey, except for U.S. Bureau of Reclamation data on inflow into Trinity Reservoir (Upper Trinity Basin). Much of the flow data used in KRIS for the Trinity Basin was previously compiled by McBain and Trush for studies related to the flow evaluation. Flow duration curves are patterned after their work. For more information see McBain and Trush (1997). Flow data for years since 1997 were downloaded from the USGS Internet site and added to flow databases within KRIS.
KRIS Map Project Integrated into Version 3.0 Database
All KRIS database projects have companion ArcView projects for the geographic area covered and most themes are now included in KRIS Version 3.0, which has a new built in KRIS Map Viewer. Nearly all map layers have a readily-accessible companion metadata file that describes the map layer and provides contact information for the source of that layer. If KRIS is installed on your computer's hard drive and you are viewing maps using the KRIS Map Viewer (the map tab), you can view metadata for a layer by clicking on a layer in the map legend to make it the active layer and then clicking the "M" (metadata) button on the toolbar. If you are browsing KRIS on the www.krisweb.com Internet site, or viewing the web pages included on the KRIS CD-ROMs, you can view map metadata by clicking on a metadata link at the link at the bottom of a map page.
The Upper Trinity KRIS Map project relies heavily on content from the Trinity Resource Conservation District (TCRCD), the U.S. Forest Service, Graham Matthews and Associates and other contributors. Data are acquired from various sources and re-projected, easily understood legends crafted and metadata compiled by Dr. Paul Trichilo of the KRIS project. Data are arranged for ease of use in subsequent watershed studies. Vegetation data from Landsat also comes from HSU and the Spatial Analysis Lab and was derived under the supervision of Dr. Larry Fox. To learn more about vegetation and timber types, see the Vegetation Type Background page.
