Changes in imperviousness for U.S. urban areas, 1974-2012

This product consists of two sets of imperviousness calculations for 3,535 urban areas and urban clusters in the conterminous United States. Imperviousness is given as the percent of the area covered by impervious surfaces, such as roads, buildings, or parking lots.

Pore water chemistry of wetlands in Interior and Southcentral Alaska, 2015 and 2016

The pore water of eight wetlands in Interior and Southcentral Alaska were collected in 2015 (17 July – 22 July) and 2016 (12 July – 16 July). Wetlands were selected to span a range in trophic status (e.g., from bog to fen). Using ultraclean trace metal clean protocols, pore waters were sampled from shallow (10‑15 cm) and deep (20-35 cm) depths below

Dissolved organic carbon concentration and dissolved organic matter characteristics in surface water samples from the U.S. Geological Survey National Water Quality Network rivers, 2008 to 2018

The sampling of 41 hydrologically diverse rivers that are monitored through the National Water Quality Network (NWQN) by the U.S. Geological Survey (USGS) took place during the water years of 2008 through 2018. Water samples were collected and filtered in the field (unless otherwise noted) using 0.45 micrometer pre-rinsed capsule filters (Versapor membrane), silicon tubing, an

Water-use data available from USGS

The U.S. Geological Survey compiles water-use estimates every five years for each State, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Archived datasets underlying the published "Estimated Use of Water in the United States" reports are available from the above link. County data incorporating any revisions can be found on ...

Hydrologic Conditions of Selected Reservoirs in Puerto Rico

The following graphs show water surface elevations above NGVD 1929 in selected reservoirs for several years, including 2015. The purpose of these graphs is to compare water surface elevations during 2015 with water surface elevations observed during years when documented droughts have occurred.

Fiber-optic distributed temperature sensing and near-surface geophysical data collected along the Santuit River, Mashpee, MA.

The Massachusetts Division of Fisheries and Wildlife has been studying brook trout populations in Cape Cod groundwater-fed river systems for decades. Recently, a notable reduction in trout population in the Santuit River sparked the concern of several groups, including the Wampanoag Tribe. Brook trout population dynamics may be tied to water quality and temperature changes, which are both

Daily Reference (RET) and Potential (PET) Evapotranspiration data over Florida, 2018

Potential evapotranspiration (PET), and reference evapotranspiration (RET) are
estimated at an approximately 2-kilometer spatial grid and daily time-scale
from January 1, 2018 to December 31, 2018 for the entire State of Florida.
Missing values are indicated with -9999.99. Missing values are due to
unavailable solar radiation data, derived from the GOES satellite. P...

Modern monthly effective recharge maps for the conterminous U.S., 2003-2015

This data set includes 1 km resolution monthly timescale estimates of the effective recharge component of the water budget over the time period from October 2003 - December 2015. These estimates were developed as water budget residuals using previously published data sets for other water budget components: PRISM precipitation (Daly et al., 2004), SNODAS snow water equivalent (National

Transient Electromagnetics, Passive Seismic, and Borehole Electromagnetics, Gamma, and Nuclear Magnetic Resonance Methods to Characterize Glacial Sediments in East Falmouth, Massachusetts, Near Nantucket Sound

A pulsed magnetic resonance borehole tool was used to characterize hydraulic properties of the aquifer. Borehole nuclear magnetic resonance (bNMR) logs were collected to measure the water content and to estimate the pore-size distribution and hydraulic conductivity (K) over the depth of the borehole. The bNMR data were collected July 25-26, 2016, and were processed August 2016.

Field measurements of water column optical properties from the Kootenai River in northern Idaho, September 26-27, 2017, and similar data from several other rivers

Field measurements of various optical properties of the water column were acquired from a single location on the Kootenai River in northern Idaho, September 26-27, 2017, to support research on remote sensing of rivers, particularly estimation of water depth from passive optical image data. The field measurements included in this data release include several parameters measured with three
