Map showing fish sampling locations within the Trinity River watershed, Trinity County, California.

Considerable mining of placer (alluvial) gold deposits, using hydraulic methods that employed mercury to process ore, took place in Trinity County, California, during the latter half of the 19th century and the first part of the 20th century (Clark, 1963; Alpers and others, 2005). In addition, mercury was mined by underground methods in the Altoona Mining district (Swinney, 1950).

During 2000–2002, the U.S. Geological Survey (USGS) conducted an investigation, in cooperation with other federal and state agencies, to assess mercury contamination associated with historical mining in the Trinity River watershed. Agencies that provided funding and in-kind services for the investigation included the U.S. Department of Agriculture–Forest Service (USDA–FS) Shasta-Trinity National Forest, the Bureau of Land Management (BLM), and the California State Water Resources Control Board (SWRCB). During 2000–2002, the USGS collected 368 fishes from 4 locations within Trinity Lake, from 16 stream sites, and from 3 pond sites within the Trinity River watershed (fig. 1; tables 1 and 2). The following species of fish were sampled and analyzed for total mercury (scientific name and number of samples in parentheses): brook trout (Salvelinus fontinalis, 13), brown bullhead (Ameiurus nebulosus, 5), green sunfish (Lepomis cyanellus, 13), largemouth bass (Micropterus salmoides, 33), marbled sculpin (Cottus klamathensis, 24), rainbow trout (Oncorhynchus mykiss, 237), smallmouth bass (Micropterus dolomieu, 41), and white catfish (Ameiurus catus, 2).
