Samples of fish from Pyramid Lake show they are safe to eat, the tribe announced, adding that the mercury levels of the fish are below federal standards for safe consumption. The tribe ordered the samples after a University of Nevada, Reno researcher released results in March of research into fish in a major Truckee River tributary. It found that carp and catfish in the Reno area's Steamboat Creek contained levels of mercury exceeding the government's standards for safe consumption. Trout in the Truckee, below its confluence with Steamboat Creek, showed levels of mercury near maximum acceptable standards. Exact levels of mercury found in Pyramid Lake fish were not released. The desert lake, about 30 miles northeast of Reno, is the terminus of the Truckee River.
