    dct:description "This U.S. Geological Survey Data Release provides data collected from Nolin Lake Kentucky, during 2016 to 2017. Two types of data are reported: zooplankton and phytoplankton data are raw calculated values not rounded to USGS significant figures and continuous water-quality data collected with a multi-parameter sonde. The zooplankton, phytoplankton, and water-quality data describe a swarm of the invasive cladoceran Daphnia lumholtzi (D. lumholtzi) Sars, 1885 in a Kentucky USA reservoir during midwinter 2017." ;
