On-line Resources

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.

Klamath Basin TMDLs

Klamath Basin TMDLs (California)

Klamath Basin TMDLs (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.

Tribal Water Quality Monitoring

Klamath Basin Tribal Water Quality Website / Selected Reports

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.

Other Resources

Klamath Fishery Portal

KFHAT was initiated by the North Coast Regional Water Quality Control Board and is made up of agencies, tribes, private organizations, and other interested individuals that share a concern for fish health in the anadromous portions of the Klamath Basin.

Klamath Watershed Institute

GIS layers for the Klamath Basin.

Klamath Basin Monitoring Program - Digital Library

Document Library is an online repository of documents relevant to the water quality and fisheries of the Klamath River.

Klamath Basin DSS

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.

Water Quality Monitoring Plan Subcommittee Blog

The Klamath Basin Monitoring Program Blog was used as tool for developing the monitoring plan. The blog allowed water quality monitoring organizations throughout the Basin respond to key questions regarding water quality impairments. The responses outlined here were critical to the development the monitoring plan.
