[1] The California Office of Environmental Health Hazard Assessment has issued a safety advisory for any fish caught in Don Pedro Reservoir due to elevated levels of mercury and PCBs.
[5] The reservoir submerges some 26 mi (42 km) of Tuolumne River bed, and has a surface area of about 13,000 acres (5,300 ha).
The two irrigation districts and the BLM control the land 15 feet (4.6 m) above the high lake level.
There are drive-in and boat-in campgrounds, houseboat areas, fishing, water skiing, and mountain biking and hiking trails.
The San Francisco Public Utilities Commission (SFPUC), of which Hetch Hetchy Water and Power is a division, provided about 45% of the funds for construction of the 1971 New Don Pedro Dam and so has the right to store 570,000 acre-feet (700,000,000 m3) of water in the reservoir.
