What's new in KRIS Klamath-Trinity Version 3.0

KRIS Version 3.0 for the Klamath-Trinity captures a great deal of new data and reports compiled since the publication of Version 2.0 in April 2001. Some studies were precipitated by the crisis of the September 2002 fish kill in the lower Klamath River, while others like the Trinity River TMDL and Klamath flow studies are associated with longer term processes. Below is a selection of key documents on emerging science in the Klamath and Trinity River watersheds. See the Bibliography page for a complete list of documents in KRIS Version 3.0.

New Klamath River Documents

	How Much Flow Does the Klamath River Need? Flow Study (Hardy Phase II): "This report details the analytical approach and modeling results from site-specific studies conducted within the main stem Klamath River below Iron Gate Dam downstream to the estuary. Study results are utilized to make revised interim instream flow recommendations necessary to protect the aquatic resources within the main stem Klamath River between Iron Gate and the estuary." This report has been held in draft and, consequently, not fully utilized as a basis for setting flow levels by government agencies and the courts. The Klamath Basin Water Users have sponsored a critique of Hardy Phase II. See Vogel 2003. Hardy, T. B. and R. C. Addley. 2001. DRAFT.

	What Caused the September 2002 Fish Kill? An estimated 33,000 adult salmon and steelhead died in the lower Klamath River in mid-September, 2002. Reports on causal mechanisms were produced by the California Department of Fish and Game, U.S. Fish and Wildlife Service and the Klamath Basin Water Users. Not all of the reports agree, but water quality and fisheries data are available in KRIS Version 3.0 for further analysis. California Department of Fish and Game (CDFG). 2003.

	Are There Native Coho Salmon in the Middle Klamath, Shasta and Scott? Discovery of hundreds of coho salmon in the Scott River basin during December 2001 and January 2002 surveys sparked a controversy over whether this species is native to interior portions of the Klamath River basin below Iron Gate Dam or introduced. The Scott River spawning survey provides compelling evidence, particularly since there were no fin-clipped fish, which would indicate hatchery origin. Downstream migrant reports in the Shasta and Scott also confirm natural production. Maurer, S. 2002.

(48 kb)	NAS 2003 Report on Klamath Endangered Fishes: The National Academy of Sciences became involved in the Klamath Basin after a critically dry year in 2001 caused the water supply to the Klamath Project in the Upper Klamath Basin to be shut off. They produced a Draft report in 2002 on the basis of flow decisions, then followed up with this more comprehensive report on Endangered and Threatened fishes. The report includes causes for decline as well as steps necessary for recovery. National Academies of Science (NAS). 2003.

Trinity River Basin New Documents

	Sediment Monitoring and Trinity TMDL Studies: The Clean Water Act requires clean up of water bodies that are listed as impaired. The Total Maximum Daily Load (TMDL) process in the mainstem and South Fork identify sediment sources, including human caused ones, which are preventable. The mainstem Trinity River has several studies pursuant to the TMDL. Graham Matthews and Associates . 2001. Sediment source analysis for the mainstem Trinity River, Trinity County, CA.

[20 Kb]	Recent Restoration Related Reports: The Trinity River Restoration Program has, as one of its objectives, to restore flows necessary to allow hydraulic function to support salmon and steelhead, but bridges below Lewiston restrict the amount of flow that can be released. One report listed below deals with bridge modifications needed to allow adequate flows. Gravel recruitment below dams is cut off, and the second study below studies sources of gravel to augment substrate supply necessary for spawning. McBain and Trush. 2002.

	Proposed Wilderness and Salmon Restoration Areas: The roadless areas of the Klamath Trinity Basin provide cool water refugia for native salmon and steelhead as well as protecting old growth habitat for many endangered and threatened animals. These areas also provide great recreational opportunities and economic benefits to the local communities.
