The Tribal Water Quality Work Group is comprised of the heads of environmental departments of the Yurok, Hoopa Valley, and Karuk Tribes, the Quartz Valley Indian Community, and the Resighini Rancheria. The group was formed in 2003, following a massive adult salmon kill in September 2002. The Work Group's stated purpose is "to prevent future disasters through sound scientific research, data analysis, and thorough planning." While the Work Group collaborates on research and shares information, it takes no collective positions, but defers to individual Tribes to offer policy statements. Each Tribe exercises authority over Reservation waters (see Tribal WQ Authority). Some Tribes also acquire designated authority as co-managers of water quality from the U.S. Environmental Protection Agency. Links to reports and other documents are available on their website. The Hoopa Tribe website provides a description of the water quality program, locations, equipment, and reports. Discrete data is available through the EPA's Water Quality Portal (WQP).

Natural Flow Study- This is a follow-up to the 2005 Natural Flow Study of the Upper Klamath River and attempts to understand how water naturally moved through the Klamath River Basin before dams, irrigation systems, and other modern developments existed, to build the most complete picture to date of the basin's natural hydrology. Local Offices: Data request forms are here. There are multiple National Forests in the Klamath Basin who have a role in monitoring, including the Fremont-Winema, Klamath, Six Rivers, Shasta-Trinity, and Modoc National Forests Streambed Sediment and Equivalent Roaded Area on the Klamath National Forest AREMP- The Aquatic and Riparian Effectiveness Monitoring Plan characterizes the ecological condition of watersheds and aquatic ecosystems to answer the core question: “Are the Northwest Forest Plan (NWFP) and the BLM Western Oregon Resource Management Plans maintaining and restoring the conditions of aquatic and riparian ecosystems on federal lands in the Forest Plan area?” Water temperature data and climate change models for the Klamath Basin are available through the Forest Service's NorWeST project. The U.S. Geological Survey website provides graphs and tables of streamflow and water-quality data from selected sites in the State of Oregon.

The TRRP is a collaboration of federal, state, and county agencies along with the Yurok Tribe and Hoopa Tribe. The TRRP is tasked with restoring anadromous fish on the Trinity River by rehabilitating the river itself. The TRRP DataPort links to multiple resources, including a document and data library, map applications, time series data, restoration database, and other resources. Through Interim Measure 15 of the KHSA, extensive long-term monitoring has been conducted in the Klamath Basin. Data and reports are available on the PacifiCorp website and on the KHSA page on the KBMP website.

Select member organizations provide water quality data through CEDEN. The California Environmental Data Exchange Network (CEDEN) is a growing statewide cooperative effort of various groups involved in the water and environmental resources of the State of California. This network is open to federal, state, county and private organizations interested in sharing data throughout the state. The purpose of the CEDEN network is to allow the exchange of water and environmental data between groups and to provide access to the public. DOTABLES is an on-line program developed by USGS that generates tables of dissolved oxygen (DO) solubility values and (or) salinity correction factors over a range of user-specified values for water temperature, barometric pressure, and salinity or specific conductance. In addition to generating tables, DOTABLES can compute a single-value of oxygen solubility and percent saturation for a specific instance of temperature, pressure, and salinity. Water Quality Portal (WQP) contains data connected to the federal National Water Information System (NWIS) and STOrage and RETrieval Water Quality Exchange (STORET), from USGS, EPA, tribes, NGOs, and academic groups. For users of WQP, there is a tutorial for the statistical program R here that outlines techniques to help retrieve and format water quality data. (California and Oregon) Sites list TMDLs developed for the Klamath Basin. Section 303(d) of the federal Clean Water Act and 40 CFR §130.7 require states to identify waterbodies that do not meet water quality standards and are not supporting their beneficial uses. These waters are placed on the Section 303(d) List of Water Quality Limited Segments, also known as the 303(d) List of Impaired Waterbodies. The list identifies the pollutant or stressor causing impairment and establishes a schedule for developing a control plan to address the impairment. Placement on this list generally triggers development of a pollution control plan called a Total Maximum Daily Load (TMDL) for each waterbody and associated pollutant / stressor on the list. CA TMDL Report Cards for Phosphorus and Nutrients, Dissolved Oxygen, and Microcystin The Klamath Fish Health Assessment Team (KFHAT) is supported by the North Coast Regional Water Quality Control Board and California Department of Fish and Game and is made up of federal and state agencies, tribes, private organizations, and other interested individuals that share a concern for fish health in the anadromous portions of the Klamath Basin. The KBMP Document Library is an online repository of documents relevant to the water quality and fisheries of the Klamath River. The Klamath Basin Decision Support System (DSS) is the vision of the Klamath County Board of Commissioners, a vision which quite simply, is to allow a broad and diverse audience access to a common base of resource data for the Klamath Basin.
