Overview
The Sierra Nevada Aquatic Research Laboratory (SNARL) was established in 1935 by the US Bureau of Sport Fisheries and Wildlife as the Convict Creek Experiment Station. The goal of the station was to study the success of hatchery trout in a native stream. Acquired by UCSB in 1973, the site now serves as a base for research and teaching in eastern and central California and western Nevada. With some of the most developed facilities in the UC Natural Reserve System and a considerable outreach program, SNARL is UC’s outpost in eastern California, a region of the state with no university campuses.
The 55-acre SNARL site is an ideal base for field research throughout the eastern Sierra and the Owens Valley. A former US Fish and Wildlife Research station since 1935, the facilities at SNARL were transferred to the University in 1973. SNARL provides a modern laboratory, which includes a molecular diagnostics facility, and experimental stream complex that promotes and encourages scientific research all year long. SNARL lies immediately at the base of the eastern slope of the Sierra Nevada, along the borderline that separates the montane environment of the Sierra from the arid Great Basin Desert to the east. The reserve provides easy access to the high Sierra Nevada, Mono Lake, Long Valley, Owens Valley, Yosemite National Park, and the Great Basin.
Convict Creek provides a perennial water supply that contributes to SNARL’s habitat diversity. Three major types of vegetation occur on the relatively uniform terrain found at SNARL. Each is characterized by floristic composition and accompanying physical features, including soil type, exposure, and water availability. The three vegetation types found at SNARL are: 1) Great Basin Sagebrush Vegetation 2) High Desert Riparian Woodland 3) Riparian Meadow Vegetation. Non-aquatic research is permitted and encouraged.
Facilities
The reserve has overnight facilities for 45 people in the form of a dormitory, a three-bedroom house (Q8), a two-bedroom house (Q1), and 2 one-bedroom cottages (Q2 and Q3). Each unit has bunks, a kitchen with pots, pans, and dishes, and restroom facilities. There is no food or custodial service. Users are expected to furnish their own food, bedding, towels, vehicles, and equipment. Housing is assigned at the discretion of the Director. See the site map and facilities for more detail.
The reserve has over 6,000 sq. ft. of lab and office space. There are wet labs, dry labs, a radioisotope lab, controlled-environment chambers, and shared laboratory equipment. More details about our laboratory facilities can be found on our laboratory orientation page. Broadband Internet is linked by fiber optic cables and can be accessed across much of the Reserve. There is ample office space, a conference room, and new classroom/lecture hall that seats 120.
Reserve Facts
Selected Research Projects
Ecology of Mono Lake
UC research on Mono Lake has helped restore the ecosystem of this critical resource for waterbirds and other wildlife. Ongoing projects include modeling and monitoring.
Sierran Snowpack
SNARL scientists operate a snow laboratory on Mammoth Mountain; the National Science Foundation and NASA Earth Observing System Project fund ongoing studies of snowpack properties and snowmelt runoff.
Aquatic Biology
Ongoing studies examine impacts of livestock grazing on stream ecology and effects of non-native trout on Sierra Nevada lake ecosystems.
Endangered Species Conservation
Ongoing studies are examining the causes of declines in populations for the mountain yellow-legged frog, and the potential for recovery of this species
