Time-lapse photography of Milford Lake, Kansas, June through November 2016
This U.S. Geological Survey (USGS) Data Release provides time-lapse photography collected from six sites at Milford Lake, Kansas, during June through November 2016. All photographic images are displayed using a .mov common multimedia format. Time-lapse cameras were used to visually capture cyanobacterial accumulations and movement throughout Milford Lake, Kansas, at one-hour intervals from June 29
Digital Datasets Documenting Fault Rupture and Ground Deformation Features Produced by the Mw 6.0 South Napa Earthquake of August 24, 2014
This product is a collection of digital data that document fault rupture and ground deformation produced by the August 24, 2014 South Napa Earthquake. These datasets are described and more fully discussed in Ponti, D.J, Rosa, C.M, and Blair, J.L., 2019, The Mw 6.0 South Napa Earthquake of August 24, 2014 - Observations of surface faulting and ground deformation, with recommendations for improving
Bathymetry and Storage Capacity of Dierks Lake, Arkansas
A bathymetric survey of Dierks Lake, Arkansas, was conducted in late June - early July, 2018, by the Lower Mississippi-Gulf Water Science Center (LMG WSC) of the U.S. Geological Survey (USGS) using methodologies for sonar surveys similar to those described by Wilson and Richards (2006) and Richards and Huizinga (2018). Point data from the bathymetric survey were merged with point data from an aeri
Bathymetry and Storage Capacity of Gillham Lake, Arkansas (ver. 1.1, April 2020)
A bathymetric survey of Gillham Lake, Arkansas, was conducted in June, 2018, by the Lower Mississippi-Gulf Water Science Center (LMG WSC) of the U.S. Geological Survey (USGS) using methodologies for sonar surveys similar to those described by Wilson and Richards (2006) and Richards and Huizinga (2018). Point data from the bathymetric survey were merged with point data from an aerial LiDAR survey c
Archive of Chirp Subbottom Profile Data Collected in June 2018 From Fire Island, New York
Researchers from the U.S. Geological Survey (USGS) conducted a long-term, coastal morphologic-change study at Fire Island, New York, prior to and after Hurricane Sandy impacted the area in October 2012. The Fire Island Coastal System Change project objectives include understanding the morphologic evolution of the barrier island system on a variety of time scales (months to centuries) and resolving
Geospatial dataset of flood-inundation maps for Cayuga Inlet, Sixmile Creek, Cascadilla Creek, and Fall Creek at Ithaca, New York
Digital flood-inundation maps for a 2.9-square-mile area of Ithaca, New York, were created in 2015-18 by the U.S. Geological Survey in cooperation with the City of Ithaca, New York, and the New York State Department of State. The flood-inundation maps depict estimates of the maximum areal extent and depth of flooding corresponding to selected flood frequencies for Cayuga Inlet, Sixmile Creek, Casc
USGS Surface-Water Data for the Nation
Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall across the U.S. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
USGS Groundwater Data for the Nation
Data from wells, springs, test holes, tunnels, drains, and excavations across the U.S.; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
USGS Water-Quality Data for the Nation
Chemical, physical, and biological properties of water, sediment, and tissue samples from across the U.S. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and dissolved oxygen.
Eutrophication water-quality models and supporting water-quality and phosphorus load data used to simulate changes in the water quality of the Winnebago Pool Lakes, Wisconsin, in response to change in phosphorus loading
Three eutrophication models (mass balance, BATHUB, and Jensen models) were developed and calibrated for the Winnebago Pools, Wisconsin. These models were used to quantify the input of phosphorus from the sediments of the lakes, and determine how the water quality (total phosphorus concentration, chlorophyll a concentrations, and Secchi depth) should respond to changes in phosphorus loading from th
GLM model data sets used to evaluate changes in the hydrodynamics of Anvil Lake, Wisconsin
Interannual differences in the water quality of Anvil Lake, WI, were examined to determine how water level and climate affect the hydrodynamics and trophic state of shallow lakes, and their importance compared to anthropogenic changes in the watershed. To determine how changes in water level may affect these processes, the General Lake Model (GLM) was used to simulate how the lakes thermal structu
Pelican Island and Pass La Mer to Chaland Pass Restoration (BA-38): Pelican Island and Chaland Headland 2016 habitat classifications
The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana's Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring (SWAMP) program. The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands, habitat types,
