Barco lake a core aquatic site is situated within Ordway-Swisher Biological Station (OSBS) in Putman County, Barco Lake is an oligotrophic (i.e., has low nutrient levels) acidic seepage lake in the mantled karst, a landscape formed by the dissolution of soluble rocks, of north central Florida. Common animals include tiger salamander, barking treefrog, spadefoot toad, gopher frog, gopher tortoise, worm lizard, fence lizard, mole skink, indigo snake, coachwhip snake, pine snake, short-tailed snake, crowned snake, eastern diamondback rattlesnake, bobwhite, ground dove, red-headed woodpecker, rufous-sided towhee, fox squirrel and pocket gopher. Barco Lake is an important breeding areas for terrestrial amphibians, including the threatened gopher frog, as well as many unusual or endemic insects, as well as an important watering holes for a number of mammals and birds, including ducks and wading birds. This site has one meteorological station located in the riparian area and one meteorological station above water on a buoy. The met stations are outfitted with the a subset of the same sensors used at terrestrial sites. Measurements include wind speed and direction, air temperature, barometric pressure, relative humidity, shortwave radiation, and PAR.This site has one buoy-mounted sensor station and an inlet station and outlet station. At the buoy, the automated instrument measurements are: PAR at water surface, PAR below water surface, temperature at a specific depth in surface water, water quality (specific conductivity, chlorophyll a, dissolved oxygen content, pH turbidity, and fDOM), and nitrate. At the inlet and outlet stations, the measurements are: PAR below water surface, elevation of surface water, and temperature in surface water. Eight groundwater wells throughout the site collect specific conductivity, water tempertaure, and elevation of groundwater.
