context_page_description: New Bullards Bar Reservoir is a large reservoir in northeastern Yuba County, California, United States, at an elevation of 2,000 feet in the Tahoe National Forest and about 30 miles northeast of Yuba City. The 969,600 acre foot reservoir is formed by New Bullards Bar Dam on the North Yuba River, a tributary of the Yuba River. It also receives a portion of the Middle Fork's flow that is diverted to the reservoir via tunnels.
  The dam is a 635-foot high concrete variable radius arch dam. It was finished in 1970 and is owned by the Yuba Water Agency, which is a special district government agency based in Marysville, Ca. It is a multipurpose dam, but its most important function is flood control, which 170,000 acre feet of the reservoir's capacity is dedicated to. While this is only 17.5% of the reservoir's total capacity, it is enough to create a medium-sized reservoir by itself. The dam also provides water for irrigation, hydroelectricity production and recreation, including boating, water skiing, fishing, mountain biking and camping.
context_section_description: New Bullards Bar Reservoir is a large reservoir in northeastern Yuba County, California, United States, at an elevation of 2,000 feet (610 m) in the Tahoe National Forest and about 30 miles (50 km) northeast of Yuba City. The 969,600 acre foot (1.1960×10⁹ m³) reservoir is formed by New Bullards Bar Dam on the North Yuba River, a tributary of the Yuba River. It also receives a portion of the Middle Fork's flow that is diverted to the reservoir via tunnels.
  The dam is a 635-foot (194 m) high concrete variable radius arch dam. It was finished in 1970 and is owned by the Yuba Water Agency (Yuba County Water Agency, formally), which is a special district government agency based in Marysville, Ca. It is a multipurpose dam, but its most important function is flood control, which 170,000 acre feet (210,000,000 m³) of the reservoir's capacity is dedicated to. While this is only 17.5% of the reservoir's total capacity, it is enough to create a medium-sized reservoir by itself. The dam also provides water for irrigation, hydroelectricity production and recreation, including boating, water skiing, fishing, mountain biking and camping.
  The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for fish caught in New Bullards Bar Reservoir based on their levels of mercury or PCBs.
  The reservoir provides water to power two hydroelectric plants, New Colgate Powerhouse and Fish Release Powerhouse. New Colgate Powerhouse is not located at the base of the dam, like most hydroelectric plants. Instead, the 14-foot (4.3 m) diameter New Colgate Tunnel carries the water about 5 miles (8 km) southwest of the dam to the powerhouse. This increases the head, which allows the plant to produce more electricity. The dam's Pelton wheels are the largest ever built and have a combined capacity of 315 MW. Some water is released at the base of the dam so that the streambed is not completely dewatered upstream of the New Colgate Powerhouse tailrace. This water powers the 150 kW Fish Release Powerhouse. In the event of a power outage, this plant can operate the dam's massive spillway gates.
  Bullards Bar Reservoir is also used for outdoor recreation. It is 16 miles (26 km) in length and has 60+ miles of shoreline. Water Ski Magazine rates Bullards Bar Reservoir as one of the best recreational lakes in the United States.  Bullards Bar is a mountain biking destination, with about 19 miles of hiking and biking trails, primarily on the east side of the lake.  The trails are maintained by the USFS Yuba Ranger District and volunteers from Bicyclists of Nevada County or.  Bullards Bar offers two boat launching facilities with one launch ramp adjacent to Emerald Cove Marina. Emerald Cove Marina offers a variety of services, such as a general store, gasoline, boat moorage, and camping as well as houseboat, ski, patio, and fishing boat rentals.
