Loftin 2017 Publication USGS Scientific Investigations Report 2016–5168 Reston, VA U.S. Geological Survey https://doi.org/10.3133/sir20165168 This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from Milford Lake, Kansas, on July 27 and August 31, 2015. All data are reported as raw measured values and are not rounded to USGS significant figures. Continuous water-quality monitors were used to measure water temperature, specific conductance, turbidity, pH, chlorophyll, phycocyanin, dissolved oxygen, fluorescent dissolved organic matter (fDOM), and nitrate (only collected at 1.0-meter depth) at thirty-second intervals at depths of 0.5-, 1.0-, and 1.5-meters throughout the lake. The data were collected by the USGS Kansas Water Science Center, in cooperation with the Kansas Department of Health and Environment, as part of a study to evaluate the spatial variability of harmful algal blooms in Milford Lake, Kansas. These data are published in support of the USGS Scientific Investigations Report 2016-5168 (https://doi.org/10.3133/sir20165168) 20150727 20150831 Publication Date Complete None planned -97.06505 -96.84209 39.25728 39.04161 Data were collected throughout Milford Lake, Kansas.

Lawrence KS 66049 USA (785) 832-3563 lrking@usgs.gov This study was conducted by the U.S. Geological Survey in cooperation with the Kansas Department of Health and Environment. All data were broadly checked for accuracy; erroneous spikes and outliers were deleted from the data. No formal logical accuracy tests were conducted, but data were checked for consistency and numerical errors. Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. No formal positional accuracy tests were conducted. No formal positional accuracy tests were conducted. Data from each deployment were evaluated. Erroneous spikes and outliers were deleted. All data were compiled into one spreadsheet for this data release. 20160318 Field data collection Spatial data were collected using boat-mounted water-quality monitors during July 27 and August 31, 2015. Multi-parameter water-quality monitors were mounted underneath the boat at about 0.5- and 1.5-meter depth, and a nitrate sensor was mounted at about 1.0-meter depth. The average boat speed was approximately 14 kilometers per hour as described in Foster and others (2016).
