These data are high-resolution bathymetry (lake bottom elevation) in a gridded XYZ format, generated from hydrographic surveys of Morse Reservoir in May 2016. Hydrographic data were collected using a multibeam echo-sounder (MBES) with integrated inertial navigation solution (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the lake along survey lines distributed throughout the area. Data collection software integrated and stored the depth data from the multibeam sonar and the horizontal and vertical position and attitude data of the vessel from the INS in real time. In the shallow areas, additional data were collected with an acoustic Doppler current profiler (ADCP) and a real-time...

Hydrographic data were collected using an acoustic Doppler current profiler (ADCP) with an integrated global navigation satellite system (GNSS) smart antenna. The ADCP and GNSS antenna were mounted on a marine survey vessel, and data were collected as the survey vessel traversed the river along planned survey lines....
In 2015-2018, the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency Great Lakes Restoration Initiative investigated the biodegradation of microcystins in source waters and sand filters from drinking-water plants in the Western Lake Erie Basin. Four source waters and three sand filtrate samples were collected from the intakes and sand filters of Lake Erie drinking-water plants and transported to the USGS Ohio Water Microbiology Laboratory, where investigators set up microcosms to enrich for and identify indigenous bacteria capable of degrading microcystins. Quality control samples were set up in the microcosms to check analyses and included positive controls, negative controls,...
This data release contains a 17-year record (2005-2022) of discrete chlorophyll data from inland waters, collected from across the nation and territories. These data are from discrete samples (collected in the field and analyzed in the laboratory) from plankton (suspended algae) and periphyton (benthic algae) from lakes, streams, rivers, reservoirs, canals, and other sites. These data are gathered to support process and remote sensing modeling and prediction of Harmful Algal Blooms (HABs). The chlorophyll data were compiled from the Water Quality Portal (WQP) and USGS National Water Quality Lab (NWQL). Data for uncorrected chlorophyll a, corrected chlorophyll a, and pheophytin from EPA Methods 445 and 446 are included...

Natural river channels continually evolve and change shape over time. As a result, channel evolution or migration can cause problems for bridge structures that are fixed in the flood plain. A once-stable bridge structure that was uninfluenced by a river’s shape could be encroached upon by a migrating river channel. The potential effect of the actively meandering Wabash River on the Interstate 64 (I–64) Bridge at the border with Indiana near Grayville, Illinois, was studied using a river migration model called RVR Meander (RVR Meander, 2011). RVR Meander is a toolbox that can be used to model river channel meander migration with physically based bank erosion methods. This study assesses the Wabash River meandering...

This data release includes meteorological and soil information collected from calendar years 2015 to 2021 (water years 2016 to 2021) that include air temperature, soil temperature, soil moisture and solar radiation monitored at a site in the Black Creek subwatershed near Harlan, Allen County, Indiana (USGS 411228084541703 MET STATION WEST OF BULL RAPIDS RD NR HARLAN, IN). Meteorological and soil monitoring was done in coordination with monitoring of flow, suspended sediment, and nutrients in overland flow and subsurface-tile flow to support understanding of factors affecting nutrient and sediment loads at paired U.S. Geological Survey (USGS) edge-of-field (EOF) agricultural sites. Black Creek is a tributary of the...
This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Nolin Lake, Kentucky, during August 15-19, 2016. The digital dataset includes samples collected at six U.S. Army Corps of Engineers (USACE) sites on Nolin River Lake. Phytoplankton were identified to the lowest possible taxonomic level and abundance (density) and biovolume are reported.
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.
Site-specific multiple linear regression models were developed for eight sites in Ohio—six in the Western Lake Erie Basin and two in northeast Ohio on inland reservoirs--to quickly predict action-level exceedances for a cyanotoxin, microcystin, in recreational and drinking waters used by the public. Real-time models include easily- or continuously-measured factors that do not require that a sample be collected. Real-time models are presented in two categories: (1) six models with continuous monitor data, and (2) three models with on-site measurements. Real-time models commonly included variables such as phycocyanin, pH, specific conductance, and streamflow or gage height. Many of the real-time factors were averages...

Rainfall and runoff data were collected during non-winter months between 2018 and 2020 at 10 rain gages and 12 calibrated H-flumes located in Ohio Department of Transportation (ODOT) highway median-strip catchments. The data were used to compute event-based summary statistics of rainfall and runoff. A rainfall-runoff “event” was defined to begin at the time of the first measured rainfall and end when rainfall and runoff (if any) ceased and remained ceased for at least 3 hours. The summary statistics (along with selected metadata) are included in this data release.

A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration, and divert stormwater from city sewers. In order to investigate the impacts of the installed SCMs, hydrologic data were collected prior to and following the installation to estimate site water budgets (Lampe and others, 2022). The Episodic Master Recession (EMR) method was used to estimate recharge rates at five different locations for inclusion in the site water budgets (Heppner and Nimmo, 2005; Nimmo and others, 2015). Input data for the EMR software package were collected from a rain gage and five monitoring wells with installed pressure transducers at different locations...
