The South Fork Little River (SFLR) and the North Fork Little River (NFLR) are two major headwater tributaries that flow into the Little River just south of Hopkinsville, Kentucky. Both tributaries are included in those water bodies in Kentucky and across the Nation that have been reported with declining water quality. Each tributary has been listed by the Kentucky Energy and Environment Cabinet—Kentucky Division of Water in the 303(d) List of Waters for Kentucky Report to Congress as impaired by nutrients, pathogens, and sediment for contact recreation from point and nonpoint sources since 2002. In 2009, the Kentucky Energy and Environment Cabinet—Kentucky Division of Water developed a pathogen total maximum daily...

We describe swarming behavior in the invasive cladoceran Daphnia lumholtzi Sars, 1885 in a Kentucky, USA, reservoir during winter 2017. The taxon is a highly successful tropical invader and has spread throughout the lower latitude systems in the USA since its discovery in 1991. Other than a few isolated reports, the abundance of D. lumholtzi is often <1 organism L-1. Previous studies indicate that D. lumholtzi is a largely thermophilic species often peaking in abundance in late summer after native daphnids are gone from the water column of lakes and reservoirs. Prior to our study, there have been no published reports of swarming behavior by this species. We document the occurrence of massive swarms (>10,000 organisms...

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.

The U.S. Geological Survey (USGS), in cooperation with the Little River Water-Quality Consortium (LRWQC), collected water samples at 19 sites in the upper Little River Basin, Kentucky, from November 1, 2012 to November 30, 2014. This digital dataset contains site information, analyzing laboratories and methods, and water chemistry for these samples. Water chemistry results include concentrations of nutrients, suspended sediment, dual-nitrate isotopes, Escherichia coli, and microbial-source genetic markers.
